    'Natural Gut Wholesale' Review (Stringing and Play)

    I use string savers liberally on my full bed of gut and apply Carnauba car wax on the string after each session, and my gut lasts a really long time. Yeah, string savers are not that cheap to be used liberally, but if you don't mind reusing them, then the cost is not that bad. People think...

    Pressureball tube, any experience?

    I received the new profile replacement slides (and a new replacement tube as well) from Barry/PressureBall free of charge as promised. I tried out the new slides and they indeed perform and hold pressure much better than the old slides. My tubes have been under pressure using the redesigned...

    Pressureball tube, any experience?

    I can attest that Pressureball/Barry replaced the 3 slow-leak tubes I sent back plus he added another new one to cover for my cost of postage to send the 3 original tubes back to New Zealand from the US which was not cheap (around $15?). But, one of the new ones now has a major leak at the foot...

    Tennis and Golfers Elbow - aftermath

    I thought magnesium usually is to sooth muscle pains. Since tennis elbow is related to the tendons/ligaments and not muscles, I'm not sure how much it'll help.

    Tennis and Golfers Elbow - aftermath

    Magnesium is basically what's in epsom salt. You can just soak your elbow in water with epsom salt for the same effect. That's what people do to relieve sore muscles, epsom salt bath. Not sure how much the magnesium oil is but epsom salt is pretty cheap.

    Recommend tension: gut string PLUS TE string tension strategy

    It seems like the majority is advocating stringing natural gut at 60+ lbs for any chance of control. I'm the minority who tried out natural gut at 40 lbs and like it and still able to keep control. But I'm not a big power hitter in the first place though. Natural gut at 40 lbs gives me the...

    Yep, that has been my experience, too. I'm used to great service almost everywhere else, at least when it comes to notification of shipment and tracking numbers, etc. But not these guys. They just don't bother. If you're patient enough, eventually you'll get it in the mail. If you're not...

    I also use the Dunlop 4-can tubes with the flat bottom like yours and I was able to slip the bottom on OK. Not easily, with a bit of effort, but not so bad that the tube looks damaged afterward. I found that if you don't screw the washers on tight enough, the tubes will leak faster. If you...

    Yes, I have the exact same poor (actually non-existent) email response and slow shipment and notification like you said with them, too. The only way I can get attention was to call their phone number directly. Some day I'd call several times and nobody answered the phone. Voicemail is as...

    How To Pressurize / Revive Old Tennis Balls...

    I agree that when balls lose ALL pressure, it's best to dispose of them than to revive them. When balls lose just a little bit pressure but the felt is still fairly new, it'd be worth recharging them. But it's best to use these pressure tubes to keep the balls from losing any pressure in the...

    How To Pressurize / Revive Old Tennis Balls...

    It's possible to revive completely dead balls in my opinion, but it would take much longer to do so. First you'd have to find the pressure point just before they collapse. Being completely dead balls, that pressure point is going to be pretty low (15-20 psi). Then you may store them in there...

    How To Pressurize / Revive Old Tennis Balls...

    If you already have the PressureBall tubes, I don't see why you need to retire them. I have both types, too, and my strategy is to continue to use the PressureBall tubes to add pressure to flatter balls, since you can't put flatter balls under too much pressure anyway or they'll collapse. And...

    How To Pressurize / Revive Old Tennis Balls...

    You can reduce pressure to r Yes, the ball will pop back out if you slightly reduce the pressure up to a point. In fact that's the only way to pop the ball back out. But I want to clarify that if you just stop at that point where the ball pops back out, it will have been too little pressure by...

    How To Pressurize / Revive Old Tennis Balls...

    The easiest way is to play them often enough so that they go bald before they go flat. That way you don't have to worry about repressurizing them. Another easy way is to just leave your balls behind at the court for somebody else to enjoy them, if you know that they'll go flat by the next time...

    My new Zombie tubes (the thicker top) are working out great. I wouldn't recommend the old top, but the new thicker top seems to hold up pretty well under higher pressure now. Their website is still showing the old pics of the top. Aldric Lee said they were going to update their site with the...

    Tennis and Golfers Elbow - aftermath

    Given the extent of your TE treatment for recovery, beside TE friendly rackets, I would consider a full bed of natural gut on those rackets as well. Or at least a hybrid of gut and multi

    If yours is still under warranty and it cracks under normal use (then you should be able to call in to ask for a replacement. What pressure do you normally set your Tennis Ball Charger at? One thing I notice is that the flatter balls will collapse at higher pressure. So if you have a mix of...

    I received my ZT-1 top replacement today. Below is a pic of it side by side with the old top. As you can see, the new top (on the right) is much thicker. It's also carved around the edge to allow the top to be put in place without having to remove the wingnuts. I thought that was a very...

    I spoke with Aldric Lee of Zombie Tube some more this morning and he said that they're now shipping their redesigned version. He said that the bottom is the same, but the top has been made thicker to avoid cracking. He told me that since I reported my issue to him of my cracked top, he's also...

    Just FYI, I was able to get a hold of somebody at Zombie Tube this morning after a couple of tries (somebody named Lee). He told me that my case was the first one that cracked at the top out of the last batch of 300 that they sent out. He said that there were a couple of cases he heard back...

    How To Pressurize / Revive Old Tennis Balls...

    I think it's the area where the valve meets the acrylic. I just can't see the plastic can being porous. It may also be at the lip of the plastic can where the metal ring wraps around that lip. They probably design the metal ring at the lip to withstand 15 psi but anything higher than that...

    Does your ZT hold pressure well? I pumped one up to 25 psi yesterday and today it came down to 15 psi. I only have the ZT-1 so I have to measure mine with an external gauge. But I have a pretty high quality accurate gauge so that's why I opted for the cheaper ZT-1. I notice that you have the...

    I didn't hear back from the Zombie Tube people today yet about my replacement request for my cracked tube. Their website says 24 hour response and I emailed them last night (almost 24 hours ago). I also called a few times this morning during business hours but nobody picked up. Left a message...

    How To Pressurize / Revive Old Tennis Balls...

    One thing I really don't like about the design is that their wing nuts don't use any washer. So there's definitely a risk of over-tightening them and cause cracking like you said. Or over time the wing nuts will wear down the acrylic top for sure and will cause complication that will...

    I received my ZT-1 Zombie Tube order a couple of days (for three 2-pack bundle totaling 6) and starting using them. I put 25 psi on them and they seem to hold up fine. Today I tried to put 30 psi into one that has fairly newer balls according to their online instruction. It seemed fine but a...

    I emailed Zombie Tube about possible further discount if I bought more than a few bundled pack of 2 on 12/22 and never heard back from them. I went ahead and ordered 3 bundled pack of 2 (for 6 ZT-1 total) on 12/26 anyway at their advertised price. Never got any email confirmation from them...

    One trick Barry Mulder of Pressureball shows me to help fix the leaky tube is to leave the clamp on the tube as is and deflate it and pour hot boiling water over the clamp area for about a minute on each end. I tried it and it seems to help a little bit but eventually it starts leaking again...

    Yep, that's what Bill Dirst from Rebounces told me, too (about $20 for a 20lbs tank). But the tank will cost $144 up front as well, in addition to his Mini GTM. I asked him the exact same question -> doesn't the CO2 (assuming that it's CO2, he didn't say exactly) passes through rubber easier...

    Rebounces are coming out with Mini Green Tennis Machines in 2 version, 30 balls and 60 balls cans. You must use a special gas to re-pressuring the balls, though. So it's not free air. They claim the cost for local refilling of the gas should cost you about 1 cent per ball. But those machines...
