### 1/5 — Don’t get!!!1

*2023-11-01*

The clock does not work, it stays frozen at the time it turns on, and the videos of the tanks are very short.

### 1/5 — Ne fonctionne pas.

*2020-11-29*

Passez votre chemin, l’application ne fonctionne pas correctement.

### 1/5 — Ne fonctionne pas

*2020-10-26*

Bonjour,
J’aimerai un remboursement car l’application ne fonctionne pas ni sur Apple TV ni sur iOS.
Ça fonctionne 10secondes puis ça bug et on revient au menu.

### 2/5 — Short videos

*2020-07-02*

Quality of the videos is ok but there is only a few seconds of video for each aquarium on a repeating loop that is quite obvious.

### 1/5 — Not worth it

*2018-12-18*

The videos appear to be 14 seconds in length and then looped. The videos really aren’t that great, if they are 4K they should be of more stunning subject matter. I could make 4K video of paint drying but that doesn’t mean my video is awesome. Also, my biggest gripe is the time doesn’t stay synced. My main reason for buying this was to have a big clock with a nice background. Well the time starts to lag immediately and after 10 or so minutes the clock is way out of sync. After around 20 min it was about 15 minutes off. I emailed the company but heard nothing. Wasted money.

### 3/5 — My review

*2018-07-15*

I enjoyed some of the videos and use my Apple TV and mirror cast the video and it looked really good.

I would suggest a few items to improve the app.

1. Have a setting to fade the bottom controls away. This is partially distracting from the videos.

2. Increase the duration of the video to say  five minutes before you looping the video over.

### 1/5 — 10 Second clips....smh

*2018-06-24*

DONT BUY! A Good selection but the clips are so short the loop is annoyingly obvious.
