Works well and easily connects to Alexa. You can control many features of supported LED strings like color and brightness with voice. Supports both WiFi and Bluetooth.

Works as it supposed to. 1.) Open screws (with provided screwdriver) 2.) Put in power supply wires 3.) Tighten screws so wire stays 4.) Put in connecting wires for lights/device. 5.) Tighten 6.) Download BanlanX 7.) Plug in, connect, and use. It’s a good controller that does what it’s supposed to.

The setup turned out great. The LEDs are white-tunable and RGB. The controller supports individually addressable LEDs, which allows for some great animations. And the transition between colors is very smooth! Configuring the lights was tricky, and took me several attempts to work it out. For the LEDs referenced below, I've provided the configuration that works. Connecting to Alexa was straightforward when you follow the directions, but not intuitive if you try to figure it out on your own.

Easy to use, quality product

I've had four of these for a little over half a year. I control them through google home, and they frequently loose connection. Less frequently, they (one at a time) will spontaneously turn their LED strips on or off. Other than that, they're easy to set up and easy to use.
