### 1/5 — Still doesn’t support version IV of device

*2025-01-11*

Will not pair to Light Master IV no matter what I try

### 1/5 — Worthless app

*2024-07-13*

Doesn't even calculate duv

### 3/5 — A bit basic

*2024-06-24*

Promising hardware but the App interface is  very limited and has not been updated in a long time.

### 1/5 — Nothing I do will allow me to connect with a light master 4

*2024-02-21*

Without the app this device is useless, and the app simply does not work. Has anybody gotten it to pair?
