## Most critical reviews (6 lowest-rated)

### 1/5 — Nothing works

*2021-06-17*

Nothing works

### 1/5 — Crap-App

*2021-01-13*

No documentation of battery-installation to player and/or motor. 
No clear indication of bluetooth connectivity. Motor starts stops randomly. Uncredibly buggy app! Not worth to buy equipment with motor!

### 2/5 — IOS 14 issue

*2020-09-19*

Does not play music for the piano on iOS 14.  Ok on an iPhone 4S but not iPhone11!!!  Please update.

### 2/5 — Bluetooth player not working with app

*2020-08-14*

I have the XQGQ-01 set and I tested the function before building it up. If I connect the player manually with the Iphone it works like a bluetooth audio box, so this is ok.
But if I connect it to the app (bluetooth button is yellow) and I want to play a key, only the motor works, but the player makes no sound.
Maybe the developer can help me, but until then I can only give 2 stars.

### 3/5 — I like it but

*2021-01-08*

### 5/5 — R/C wheels
