## Most critical reviews (4 lowest-rated)

### 1/5 — Poor product. Do not use it

*2022-08-27*

I just used a few weeks. Data can not load or connect often. Worst thing is my account keep get locked and not able to reset password. Always ask you send email but go no where. Poor apps I never seen in the world.

### 1/5 — Coollang tennis sensor and app

*2020-01-31*

The sensor is of little value,    It does not recognize the shots properly and provides no spin, sweet spot analysis.    The speed estimations are way off and it only provides a summary instead of a shot by shot view.  
The App is even worse,    The video sync does not work.     it is useless to film your shots.   The video recording does not work properly with my iphone 8.      And when i try to play aa video it shuts down the app. 
Worse sensor app combination ever.    Complete waste of money

### 1/5 — Complete garbage

*2016-12-23*

This is an attempt to clone the Sony sensor. This just doesn't work, it's complete rubbish.

### 1/5 — Hopeless

*2016-11-13*

Its registration via email ( I don't use face book) doesn't work. So I will be returning this to the shop unless this bug is immediately fixed.
The app at this stage doesn't communicate other than saying 'fail' - irritating beyond belief
