    ^ From TW link.
    Does the manufacturer really claim that 0.6oz (18 grams) is barely noticeable?! An overgrip doesn't seem enough to mask the ridges created by this racquet mount either.

    Also, since the sensor itself weighs 6 grams, could it be possible to minimize weight by putting the sensor directly inside the butt cap to avoid the 12 grams added by the mount? If not, this product seems rather impractical.

    Ahhh! Missed the deadline. Would have been really interested in demoing this product.

    I am very interested in the performance of these products from a coaching standpoint. They all have their pluses and minuses. The Babolat Play Pure Drive integrated design is optimal for Pure Drive players. It would appear the integral mounting would provide the most accurate results.

    The portability of the Zepp has it's advantages. Players using multiple racquets or demoing racquets can compare their hitting between racquets quantitatively. I am curious to see the accuracy of the results and if the mounting method affects the results. In addition, the mounting appears as though it will interfere with players like myself who grip the over the end of the handle.

    At a quick glance of the app screen shots, the Zepp doesn't provide the shot placement analysis of the PPD. Also, the PPD quantifies the level of spin.

    Actually, he did. They edited the original post @ 9:30PM last night and added the following:
    I'm really hoping for this test. I coach a high school team, and practice starts in a few weeks. If I find it useful, I'd like to try it out on a few of my players as well.

    Bingo !

    18 grams added to the buttcap right where my hand is gripping the racquet :( :(

    Even it weighed 6 grams, that mounting system looks most cumbersome- no way I want to play tennis with that mounting system on my handle. Seems after market buttcaps with the sensor inserted makes much more sense.

    I'll pass and wait for ZEPP tennis version 2.0 if they make one with an integrated system in the buttcap.

    I sent my email in at 9:24pm last night so I'm hoping I sneaked (as a Southerner 'sneaked' doesn't sound right) in and get chosen! :grin:

    As far as the product I love the fact that you can apply it to any tennis racquet which would allow you to compare your statistics to other people you play with or compare the 'numbers' to other racquets you play with. To me, this (along with the cost) is a huge advantage over Babolat's racquet.

    We sent out emails to the chosen participants. There will be a delay in this playtest so the company can perform some software updates. Please reply to your confirmation email, so we know you are aware of the delay.

    Well, I have tested the Zepp sensor here in Switzerland, and man is it buggy! Don't understand how they can put an untested product on the market. First I kept getting other players data on the iPhone app. Finally, after 5 days of emailing screen shots, they resolved the problem a week ago. Now, however, the statistics are way off. The power scale (similar to Babolat's) with a max of 100, shows my average power on the forehand to be about 11! I am not Federer obviously, but can still manage to hit with power. I informed them, they told me to reboot the sensor, which I did, and still no better. Still waiting for an answer, but I have lost confidence in the product and their level of professionality. Don 't these products get beta tested?

    Software updates

    The post above mentions some software updates.
    I would suggest to investigate the issue.
    Maybe climate in your country (is it Switzerland ?) is not very friendly for tennis?

    I would hope updates were being done from a centralized server... (Lugano is a semitropical climate as opposed to the German-speaking cantons.)... :)

    Version number

    Software should have a version number.

    Is a bad Zepp sensor better than a bad coach?

    Absolutely
    important areas for coaching using a sensor:
    1.a power number
    2.spin
    3.swing path
    4.evaluation of strings and a racket
    5.which part of strings/face of a raket was used for a given stroke
    The value of item #5 is very disputable

    Watch out for that middle link, it'll suck you in.... He said 2 1/2 hours later from watching TW reviews and TW racquet stringing completion....

    The Sony and Babolat appear the most impressive.

    I am 99% sure the Zepp won't work with folks like me who grip over the butt of the racquet. Plus, it doesn't give string bed contact data. :(

    String bed contact data?

    How would u use string bed contact data?
    It is a serious question.

    I'm curious to see where I'm contacting the ball expressed in quantitative terms. I want to see how it changes based of varying conditions, opponent, wind, court, night play. When I play at night, I want to see how my game changes because I frame a lot of shots at night.

    With the data, I'd like to see if I can clean up the consistency.

    Can you add to my list?

    Serve

    There are multiple interesting points here.
    I coach tennis-for example serve does not have to be hit at a center

    I notice my string wear (breakage) is from the PWS to the 2nd cross at the top on a Juice (bought for $40 brand new CL:) woohoo!). In the past, my Wilson FPK95 & BLX PS90 would break the mains at the top of the PWS area. There is nothing up top with the FPK or is it my conversion to the modern forehand stroke on the Juice?

    Yes, my contact is higher up in the string bed on serves (including a few shanks ...lol). I'd like to see exactly where I'm contacting with a data pool of ~~300 flat and ~~300 kick serves.

    Perhaps it'll be a novelty and it would wear off after a month of fiddling. Who knows.

    Does the Zepp's software get any better? Sony looks better in showing contact zones on the string bed and video synchronization.

    I was very close to ordering one of these since I had a 30day money back guarantee but I realized they do not show you the area of the racket you are hitting the ball. After the Babolat Play demo, I thought there should be more the zepp did.

    Yeah... the Sony looks better... Problem is it will only work on Yonex racquets.

    I was told/press info that Sony will have a product in Japan first.
    I am in US so I will not be able to test/see it soon

    I was going to order one to test since it has a 30day MBG but the app doesn't show you where on the racket you are hitting the ball. That is important to me.

    It will be great if you can get one for reference. Anyways, "appcessories" products biggest downfall is not the hardware but the app itself.

    I work in a fairly large MNC that produce tons of these "appcessories", and it always sad to see projects being put on hold or products being recalled because no one ever realises the challenges the project team has to face with regards to software.

    BTW, Sony's user interface seems much cleaner and there seems to be an live update on each shot.

    Chris Edwards

    Switching gears a bit-
    I put some questions for Chris Edwards in the TW Questions section.
    There are three posts already,two of them answered.
    You may try to check overthere from time to time.
    Yonex/Sony is a dead horse for me except of the issue of a golden/silver standard.
    As you probably know I do coaching

    I think the Sony one will only work properly is paired with few Yonex frames (at launch at least). It's a bit restrictive but a much better approach than providing fewer stats.

    PS I'm sorry I've just noticed that somebody else posted this information.

    Sony in Japan?

    I see that you are from New York
    The news is that a first release of Sony sensor will be in Japan only.
    So Sony will NOT be available in US in next 6 months or maybe even longer.
    Sorry bringing bad news.
