HAMRVL WS2811 WS2812B Wireless Mini RF LED Remote Controller 21Key 300 Color Modes SP103E for DC 12V LED Dream Color LED Strip Module Pixel Light Lamp

Directions on this unit are a bit sketchy. To make it operate properly you will need to set the RGB sequence based on the type of LED, and also the number of pixels that are in the string. That said, the direction say to "press the auto button in the off state to enter settings." I tried pressing the auto button 10-15 times in the off state and nothing happens or the string turns on even though the on button was not pressed. After multiple attempts somehow the controller finally went into settings mode. I looked on youtube and this procedure should be as simple as a one time push of the auto button. So either mine is defective, or other brands of this same product seem to work much better. The controller doesn't like mixing of different brands of LED strips even though they should be build using a standard chipset. It also seems to stop working the minute you cut you strips. My advice - works okay with a full string of lights but very difficult to get it into setting mode - if you plan to cut as part of your implementation look elsewhere.

This remote allows you to control LED's that are individually addressable, WS2811 and WS2812, and normally are controlled by a DIY microcontroller like an Arduino or a Raspberry Pi, but without any coding. The only downside is that the modes are sequenced 1 - 366 but if you want to get back to a mode once you've turned off the device you must press the mode button as many times as you had to get to that mode. So you want mode 122, you have to press the mode button 122 times if you turn of the controller. But it really does the trick and it's super brite!

Used it for an infinity mirror. Can pick amount of leds you are using with the program setup function. The controllers I've purcgased in the past seem to malfunction or stop working after time. Glad this one worked and that it's simple to use from a good distance away. The wifi one I would stay away from. Keep it simple and enjoy the light effects.

These are great units. I own a few of them. The only drawback is that they all run on the same frequency, as far as I can tell... so if you have several nearby and on, they all answer to the remote command - however, this can be desired if you’re looking for uniformity in brightness and pattern.

Ordered several for a project. Out of 4, only 2 worked. One of those 2 started flaking out after 2 weeks.So, a terrible quality rate. Maybe you get a good one, maybe you'll go through 3 returns before you get a good one.

Works well / on par with or better than most of these cheap controllers. I'm using them in my home and they haven't failed yet.

My daughter lost the original remote and I found this one which was an exact match. I didn't even have to change the connection. I just hit the on button and the lights worked.

Worked for two days
