Review on Coollang Koospur Bluetooth Tennis Racket Sensor Tracker: 🎾 Motion Detector Analyzer for Android and iOS Smart Phones (Black) by Joe Glass

Revainrating 1 out of 5

Do not buy if you have Android

I was very satisfied. It looks great so I ordered it. When it arrived, I opened the manual and scanned the app's QR code. It went wrong. I tried the one on the box and it didn't work either. I searched the store manually for the app and manufacturer. Nothing. Bottom line, it doesn't work on Android and it seems like the company doesn't really care that it actually works since they don't even have the app they link to. I started my return within 15 minutes of delivery.

Pros
  • Inspires confidence
Cons
  • Out of style
