### 1/5 — 全然使えない

*2026-05-27, version 3.57.160*

何回やってもサポートに相談しても明確な説明なし。

### 1/5 — Language won’t change

*2026-05-25, version 3.57.160*

Frustrating, I’ve updated the language to English multiple times, the operation manual remains in Chinese.  I tried to register, it won’t let me.  This doesn’t work.

### 1/5 — Not working, not up-to-date

*2026-01-21, version 3.57.160*

The app is not working properly, I am not even able to download it. Tried support and it is clearly disabled.

### 1/5 — Does not connect

*2026-01-10, version 3.57.160*

The instructions on how to connect with an installed light are unclear and not successful. In the end the app is utterly useless.

WLAN Verbindet sich nicht

### 1/5 — App says to update but there aren’t any

*2025-12-06, version 3.57.160*

This app sucks it worked for awhile and I was able to change the color on my flood lights but then all of a sudden it quit working and advised to turn on my the Bluetooth on and update the app
My lights are stuck on one color and I can’t change them anymore for the holidays

### 5/5 — Says need update app but none available

*2025-12-05, version 3.57.160*

So now I have a bunch of landscape lights that I can’t 
use because the app is broken and there is no update. Junk company- do not buy and return if you did

### 1/5 — Literal está en chino configurar

*2025-11-29, version 3.57.160*

Súper difícil de configurar, no es clara en si se debe una por una luz configurar o porque solo detecta la mitad de mis luces. Ya estoy pensando en tirarlas y mejor conseguir una marca conocida
