### 4/5 — KATSEYE

*2026-08-15*

So I rlly like how I could change the color but before I actually understood how to turn on the BLE is was SO confusing. Now it works good but I turns off every 5 seconds. 🫩

### 4/5 — Good

*2026-08-13*

I left out a star because it takes soooo long to connect like my lightstick was flashing blue but it wouldn’t connect for a long time but the changing color thing works perfectly

### 1/5 — Barely works

*2026-07-11*

This app is a scam. Do not get it. It doesn’t work at all. It says BLF disconnected. Please try again. Doesn’t work at. Also do not get it.

### 3/5 — My BLE is not connected?

*2026-06-12*

I followed the steps but when I tried to change the color it immediately said "BLT DISCONNECTED would you like to reconnect it or no?" I cliked yes and the cycle kept ongoing. I only tried it one time without errors. ONLY ONCE

### 5/5 — Yesss

*2026-06-02*

### 3/5 — I’m kinda confused

*2026-05-15*

So I don’t know or understand how to connect the light stick so my question is how do you exactly connect it????

### 5/5 — Nice

*2026-05-10*

Other than paring it with a concert seat/ticket or using the colors/dancing to music/Bluetooth there is not much although I understand that it’s just an app for a lightstick but other than that it’s so helpful overall I love it and you can control it with your phone or iPad etc

### 2/5 — How do I connect it

*2026-01-28*

My I would turn my lightstick blue like it asked and then five seconds after I could turn it different colors it would say that my BLT was not connected and then it would put me back at the page saying to hold in the two buttons. It also would take forever to load.
