Extremely long road with this entire process, but it looks like they’re finally getting close to the end. Hopefully they’ll delivered by February.

Not yet, they’re saying it’ll be here soon. The Slingers are being shipped to the States at the rate of one container every week. Should arrive in February. So realistically speaking, maybe March.

In their latest update, they delivered the first couple bags and released the following delivery timetables.

Week Commencing Feb 17 - North America shipments will leave from our South Carolina and California logistics centres to ship to backers.
Week commencing March 9 - EU (UK included), East Europe shipments will leave from our Belgium Logistic centre.
To be confirmed: Japan, Australia and other Asian market shipments. These units will be shipping from Xiamen, China and are delayed due to the Coronavirus. We are trying to work on ways around this, and will share more info as we get it.


They also posted a couple new videos this morning:

I'd like to see a review of these with those who have owned a lobster or tennis tutor. This thing looks slow and looks like it'll break pretty quickly.

yea..based on the specs... it's slow..top speed is only 40+mph

I just received my shipping info.. mine is arriving this coming monday!

also received a letter from them.. getting lots of free stuff!
  1. Oscillator
  2. Telescopic ball tube
  3. cell phone/camera holder
  4. triple racquet bag
  5. remote control
when stock is available.. a case of 72balls of Wilson Triniti!

i guess this is their way to make up for the long delays... (y)

The video looks like it's going to be a crap product. It's only one wheel/then the ball is press against a metal plate. Lobster, Tutor, Silent Partner, every other company uses 2 feeding wheels for speed/spin. If one wheel was better they would have saved costs, weight, the machine would run twice as long. This thing is going to be slow.

The kicker is they know it so comments are disabled.

Also the phone holders are a few bucks on ****/ball tube is a few buck, bag is near worthless. The oscillator/remote are the only things worth anything.

I hope people actually get good usable product but I don't see it happening and I've probably been hearing about delays for this thing for years on end

There's only one wheel?! Hmmm...

Also the attacheable plate on the bottom looks a bit weak...
Look at the video looks like only one wheel and the ball is squeezed between the wheel and the metal plate.

I don't know if they are just happy with the millions of dollars they got, minus the cost to get these out or if they are going to disrupt the tennis machine industry.

My Slinger came in tonight!! I waited at home all day today for the delivery and of course FedEx delivers it when I leave for work.:-D

A little pricey, but I went ahead and ordered a case of the Wilson Triniti balls. To me they’re an investment, plus I could always sell or keep the Triniti balls that Slinger eventually sends.

Eighteen months ago I wrote on here and said I didn't expect to receive my Slinger in October 2018. I'm happy to say that 16 months after the original delivery date, I received my Slinger today. I have it on the charger right now and I hope to break it out this weekend. I already have a league match so I don't know if I'll have time to use the Slinger, but I will try. I originally paid extra for the oscillator and remote start\stop. They are apparently sending those free to original backers and I've read from others that we may be getting reimbursed for our extra payments. We'll see if that happens.

I’m in the same situation. I payed for the extras too. I’m waiting for things to calm down a bit and see what they offer.

people been waiting years for this, some getting and no reviews?
I received mine Tuesday night, however I haven’t had a chance to use it yet. I’ve had matches or block time everyday and this week. I plan on taking it out to the courts on Sunday. It’s charged up, I have my Wilson Triniti balls and I’m ready to hit.
 
I'd love to see some reviews. I bought one on Kickstarter for my kid way back but ended up getting a refund because the machine only did half the speed advertised and didn't look anything like the prototype. It also has permanent topspin, no vertical oscillation, no drills, the remote is just on/off (ie no speed change, etc) and it's huge compared to other machines, but then what do you want for a few hundred bucks.

Got my Slinger Bag! It is sturdier and the quality is way higher than I expected it to be (considering that this was a Kickstarter product). Haven't taken it out yet, but I did turn it on in my garage to see how loud it is. It's pretty quiet! Will return with comments on the unit once the rain gives up.

got mine last Monday 2/24.
and did an hour or so testing on Thursday.
I had mostly decent used Pro-Penn Balls..

1 machine carries all, 100 balls, 3 racquets, water bottles, ball pick-up tube. etc.
the machine is huge..but it takes up less space comparted to hauling my Silent Partner, Nike racquet Bag, and Gamma ball bag/Hopper.
Looks a lot better than the original Prototype. Build quality is very good.

the machine is really quiet compared to my Silent Partner Edge.

the Ball Boy Feature is pretty nice to have...
you can just stand there at the service line and have the ball tossed to you everytime.. and not stuff your pockets
with half dozen balls.

yes its heavy on the top-spin.. but at advanced level 45mph top speed.. I was pleasantly suprised that it had plenty of pace...
more than enough for basic ball drills.

Oscillating base is works well.. and will gets your heart pumping all over the court.

basic on/off remote for ball feed and Oscillator. No loss of signal from over 2 courts away.
but machine lacked manual controls.

More advance players on the court saw the machine and were very impressed. especially after they heard what I paid for it.
and wanted to get one... sorry to tell them.. Kickstarter was all sold out. One offered to buy my machine for more than what
I paid.! I will probably sell this when I get the Hydrogen Proton Smart machine later this summer.

for under $250.. this was worth the wait. no complaints. very happy with it.

Received mine last week and tend to agree with all of the above. I'm not sure what the final retail price is going to be (I assume around $500?). At that price, I think it's still a good value, especially for High School teams, private coaches, etc. At the Kickstarter price, it's a steal.

No video yet, but I’ll post my initial thoughts on Slinger. It did NOT disappoint! The balls come out with pace and an unbelievable amount of topspin. The oscillator worked great, nice angles and I even missed one or two balls ☺. I had it set on the advanced level for distribution and I ended up moving it down to intermediate. I did probably 3 rounds of oscillating and one round of straight feeds. My favorite feature by FAR is the ball boy feature. I really enjoyed having a ball tossed to me and the perfect height and speed. I only bounce once on my serve so for me it wasn’t an issue but those of you that have a long service routine you might want to speed it up. Last but not least the REMOTE CONTROL, absolutely amazing! It starts and stops the Slinger and the oscillator too. It’s really well made too, looks like a car key fab.

I used Wilson Triniti balls, these balls are very heavy and somewhat on the hard side. Maybe because they were new. They do sound good though, I sounded like a professional tennis player blasting away on balls.

All and all the Slinger team made us wait a VERY long time, but you’ll be very happy with it once you get it on the courts.

edit: Just a heads up there will be a fair amount of tennis ball fluff on the courts and your Slinger after using it.

^^ball fluff... I noticed that too...

probably due to only have 1 spinning roller feed...
my salient partner machine.. the interior is always full of fluff... hardly outside of it.

haven't had a chance to weight it...the machine empty is lighter than my Silent Partner..
so far I've used it for over an hour.. 150 or so balls.
the User Manual is stating if used on Medium setting with Oscillation: 3hrs.
1.5hrs on Max Speed and Feed Rate.

i know fabric can't be as tough as silent partner plastic, but does it seem like it will hold up?
 
It’s 33lbs without balls. Battery life varies on the settings you choose. Max settings 1.5 battery life. Normal settings 3 hours I believe.
33 lbs & 45mph? They raised the money on a 12 lbs (5.5kg) weight, 80mph top speed and much nicer design. From https://www.kickstarter.com/projects/768141337/slinger-the-most-portable-tennis-ball-launcher/description

Specs

Sure it's inexpensive, but with all those zippers and a fabric shell, neither of which is likely to withstand the test of time, low speed, fixed spin level, bulky, no vertical oscillation, no drills (except for horizontal oscillation if you buy that feature), no ability to change speed or interval using the remote, inability to do DIY repairs and only a 1 year warranty you get what you pay for. I already have a friend at my court who said he'd sell it for what he paid as they just did not deliver what was promised. He said it was more of a toy to him and he doubted it would last compared to Spinfire, Lobster, Tennis Tutor, etc. which are known to still work 10 years later.

It probably does have a place for those on a really low budget but it doesn't seem to do any more than the Matchmate Rookie which you can get for the same price as Slinger without the horizontal oscillation optional add-on (if Slinger doesn't change their retail price as they have everything else) but with double the warranty of Slinger - $479 with free shipping and has a metal case that will last forever. Also, Matchmate has withstood the test of time.

I had the Match Mate Rookie and did not love it for portability. Weight maybe, but moving it around was not convenient for me at least. I have had the Slinger Bag for just under a week at this point and have taken it out twice. Overall, I love this thing. It throws consistent balls, is easy to move around, I actually like the fabric and it is a high quality bag. A few of my returns hit the bag/machine itself and it was totally fine. I guess we will see how it stands up over time...

My gf got hers. We tried it out yesterday. It’s ok. Has nice topspin but not very fast. It is not that heavy pretty easy to get around. We ordered ours the same day and live together. I have not heard about mine yet. Which is odd.

You can probably sell your second one for more than what you paid...
after players on the court saw mine and my friends machines......they're offering more for it..
 
They dropped the speed because whatever part they were using was having longevity issues. I would assume going to something beefier would add more weight and take up more room so they opted against it. I was one of the original backers too, but I'm not really upset about it. I just want it to arrive already.
That actually was not the reason. I don't know where you heard that but no doubt if it was from Slingerbag. It was their attempt at saving face buy blaming it on the part, which would have been the motor. Here is the real reason, which would be quite obvious to anyone that knows anything about motors and physics (I'm a mechanical engineer btw):

It is impossible to shoot a ball at the 80mph that Slingerbag raised their crowdfunding on when the ball is being propelling by only a single throwing wheel against a stationary surface, which is their design. Even Lobster And Spinfire with 2 throwing wheels rotating at almost 5,000 rpm each can only reach 80mph. Having just a single motor cannot create the speed required and then to make it worse the ball is being squeezed against a stationary surface, ie the Slingerbag chute. That then slows it down further since that creates friction working against the direction of the ball. What they needed was 2 of the same motors, which could have easily have been done but they didn't want to spend the extra money. I realized right away that Slingerbag did not really have a product that did what they claimed when they first posted on Kickstarter. Also, they were advertising a 12 lb weight, when just the one motor they were using weighed 1-3/4 lbs, then you have the weight of rest of the machine. I called out Joe Kafka, the creator, about this multiple times by emailing him and asked him to show me a video of the Slingerbag shooting at 80mph and his excuse was that it was 'always in the shop with the engineers' so he could not do that. As if!

Turns out I was correct. The machine is now advertised as having a maximum speed of only a bit over half the 80 mph advertised speed that they baited crowdfounders with, looks nothing like the original prototype that was advertised on Kickstarter as tested and 'ready for production' almost 2 years ago and 3 times as heavy. No one got what they paid for. It was a classic bait and switch. A friend at my court bought one (I pulled out and got a refund) and he's a cop and has a $2,000 speed meter that he uses on the highway so we are going to test the Slingerbag and see if it even does the stated 45mph. I'll report back.

Left - What they pretended to have tested and ready for manufacture
Right - What they ended up delivering more than 18 months late - A totally different design with very watered down specifications

most owners seem happy with their slinger...
That's called "confirmation bias". Folks who "believe" have spent the money and time and waited, and waited for these things to arrive. They don't want to feel like they made a HUGE mistake by sticking by the product and so they say they are satisfied with the purchase and are really enjoying their machine.

Exactly. Not sure how you can happy when you got something that is 1/2 the speed you were promised, multliple times heavier, 18 mos late and is a pretty pedestrian design compared to what was originally flogged. If it was almost the same fine, but this is a classic bait and switch. I like getting what I paid for, but that's just me...

Ehhhhhh....... I can’t say that I agree with you on that. We’re all entitled to our opinions of course, however I can honestly say for the amount the paid, I have no problems with Slinger. Am I happy about the long delays and endless amount of excuses? Of course not, but for the price even at retail of what Slinger offers, it’s not a bad deal at all. The Slinger company is in it’s infant stages and because of demand, I’m sure it will improve. They realize how much of strain the delays caused, they added a lot of free add ons and are even throwing in a case of free Wilson Triniti balls. I’m not even upset that I’m one of the backers that paid for all the extras. I know when things settle down a bit, they will make it right. (Plus I have my email receipts/invoices)

No it’s not sending balls out at 80mph, but that doesn’t mean the machine itself is lacking or insufficient. It’s a portable ball machine that delivers a lot of topspin and oscillates. I think tennis players of any level can get something from using it. The ball boy feature (it tosses you a ball to serve) is absolutely outstanding. So all in all I say it’s a good product.

The oscillating feature is not great. Hits about half the size of the court. If I were them I’d just let that feature go if there is a version 2.0.

You're really just proving my point, but I'm glad you like it.

Actually NO, not at the current price. If you read my post above and understand it you will know that having only a single throwing wheel has severe limitations. Without making the machine even larger, heavier, more complicated and a lot more expensive you cannot increase the speed or change the spin at all. For that you would need another throwing wheel motor and another throwing wheel, an upgraded motherboard, etc and the list goes on and on. At that point you will be at the cost of other ball machines that actually have decent speeds and versatility, not to mention a remote that does more than on/off.
