## Most critical reviews (4 lowest-rated)

### 1/5 — Fonctionne pas

*2021-11-11, version 1.0.8*

Ça ne fonctionne plus j’ai deux caméra neuve x 400 impossible de me connecté

### 1/5 — Rubbish camera and even worse app

*2019-11-22, version 1.0.8*

Rubbish camera and even worse app.
Regretting buying it, should have got a GoPro

### 1/5 — Glitchy as anything

*2018-12-31, version 1.0.8*

Have tried to download larger videos to my iPhone thru the app and it ALWAYS drops out and the camera just switches itself off. Ridiculous

### 3/5 — Works well when it works properly. Definitely needs improvement

*2020-02-27, version 1.0.8*

Inconsistent connection when other networks are present. App suddenly crashes when reviewing videos even when you are the only connection.
