Sony Smart Tennis Sensor - SSETN1W

I got this as a present for my boyfriend and he was super excited. It did not attached to the racquet too well so it will come off every so ofter. After a couple hits on the court it stopped working. He decided then to buy a new one (he thought he had broke it) and the new unit was damage as well and it did not charge. This product has some serious qualities issues, it is not sturdy and it malfunctions most of the time. Good idea bad product.

Bought two of these, the Japanese version and the new US version. Great tool to evaluate your performance and progress. Only issue with the tool - not easy to share your data with your coach or anyone else unless you give them your PSN userid/password. Screen shots do not work as well due to scrolling - you need to take two screen shots. Share icon is there but it brings up the camera for some reason. Another issue - it should have worked with sports cams. Does not work with even the Sony Sports cam. I understand why - I think it is the camera needs to be controlled by the app - I am guessing they are inserting tags within the video stream for shot markers. Unfortunate they did not think of a better way to sync the shot data with the video. Price is a bit steep at $200. Japanese version is $172 including shipping and handling. Works as good with Wilson racquets - comes with the same adapters for racquets. Only difference I see is the manuals are in Japanese - makes no difference. It is easy to use without the manual.

This deserves a solid one star because when it works it is really cool, unfortunately, it rarely works. Sony exchanged this product 6 times because they kept sending me products that didn't work. Finally after the 7th tennis sensor, they are offering me my money back because they say it sounds like a software issue with the device. So, I have tried out 7 of these sensors. Some of them didn't connect with bluetooth. Some didn't register shots on my phone. Some didn't synch. They all come off the racquet easily. Does anyone have one of these that works more than 3 or 4 times before it breaks?

I like this sensor and it gives interesting details about my tennis game, spin, and velocity, calories burned etc...the app works well and is easy to use. I took off a star because it does not secure to the racquet well. When I swing with a lot of top spin in comes off and flies away. this happens at least a few times for every hour played. they need to improve this aspect

This product never worked. I could not get it to turn on after charging or off the charger no matter what I did. It gets one star for the nifty tool and nice bag.

Its great product BUT it was falling of the grip. Sony needs to improve this. The app is great and simple to understand.

REVISED AFTER ONE YEAR: Revising my rating to 2 stars, as the plastic clip mechanism did not stand the test of time! Sensor kept coming off the racket clip, and each time the sensor was a little more damaged. I'm just out of warranty now, and have asked for a "repair" cost. We'll see what happens! ------------------------------------- EARLY REVIEW: Nice unit and seems to detect stroke type fairly accurately. A few small things: (1) "flat" forehand shots seem to register as "slice", so you might find your percentage of top-spins to slices unusually small. (there is no "flat" category) (2) not really sure what "server sync" is for, unless maybe you are moving to a new phone. (3) it's unclear that changing the racket type actually changes the sensor response to anything - to be further tested. (4) also not clear if the ball speed estimates are at all accurate - has anyone out there verified these? They seem to be good on a relative basis anyway. Also, at least if you have a Wilson racket, it may be possible to jam the adapter in a older racket and have things work fine. For example, it mounts fine on my older Wilson K-Surge. If it doesn't fit, you can order a new "butt cap" (and grip) inexpensively from a tennis shop (I got mine from JustTennis.net) All in all, happy so far!

Accuracy depends on position of the sensor in relation to the racquet. The problem is the mount keeps moving (not in all the rackets – I’ve installed it in four identical rackets and it was ok in two of them). So, when the mount move, the sensor becomes crazy (top spin backhands are considered as sliced backhands and so on). Don’t think it can be accurate, unless the sensor is built in the racket (like Babolat’s model). Also adds weight and a little vibration. Returned it after a couple of days.
