### ⭐⭐⭐ 







  
  
    Very nice tennis gadget
  

*by T***8 on Reviewed in the United States on January 3, 2020*

I was pretty skeptical about a product like this.  How in the world could a tiny round stick on device going to keep track of all the awesomeness of my tennis game... well, I learned 2 things... 1. It does a really good job doing it and 2.  I'm not really that awesome!I used the double sided stick-um to adhere it to the bottom of my racket.  Setup was really easy on my pixel 3.  The app installed and it connected via Bluetooth first try.One thing to note, before you start each tennis round, you should connect to the device and sync it.  If you don't, the first game will be added to the previous match stats.  Other than that, it works great.  I haven't counted my swings and had anyone measure my racket speed with a radar gun to verify the counts and speeds are 100% correct, but it's definitely in the ballpark.The things it keeps track of are: Total Swings per day, avg&max forehand swing speed, avg&max backhand swing speed, serve swing speed (remember, this isn't ball speed...it's swing speed). It also counts the types of swings you use during a match too... that I find very interesting.All in all a very cool device.  I'm not sure if it will improve my game, but it will certainly let me know if/when my game is improving.**UPDATE: (2/18/20)... well, I had to take 1 star off.  While it is still a good device to have, it keeps "self resetting" and when it does that, any stored info that hasn't been sync'd with your phone is lost.  I normally sync just before a match and then right after a match... but if for some reason it resets during the match, all is lost.  This has happened twice now, I'll 3 times a week, so twice in roughly 28 matches... anyhow, it's nice when it work, frustrating when you're having the game of your life and it loses it's data...

    is a bad monitor
  

*by L***Y on Reviewed in the United States on January 29, 2020*

I don't recommend this product ,is difficult to add on the butt of the racquet. The sticker are useless and don't worked with some cell phone.

    Not reliable
  

*by L***H on Reviewed in the United States on January 12, 2020*

I bought this for my 13-year-old to study her tennis swing. It rarely worked. The sensor did not pick up her strokes despite trying it multiple times.  It worked once and then didn’t work again. Not reliable enough.
