DS RGB Case Fans Controller Kit with 17Key Remote, Connect to DS RGB RAM Heatsink and DS PC RGB LED Strip (SATA Power Cable, O Series)

As you can read, it simply works perfectly for what it is designed for.

I've built several computers and I work in tech support. I followed the instruction manual exactly— unplug the controller from power for 5 seconds, plug it back in, and within 5 seconds, press "speed -" and "speed +" together. I've also tried every other combination imaginable on the remote, and nothing has worked. There are no obstructions between the remote and the controller. My fans are stuck on blue light all the time, the remote does nothing.

Finally got around to installing this thing and it didn't take very long to figure out it doesn't remember the settings you put it on. Every time I change the flashing settings where I want it, it defaults back to flashing the setting that it came with after the computer is shut down and I'm forced to change it back where I want it. Obviously this thing doesn't have any kind of memory. Only way around it is leave the computer running. Funny thing is, a friend gave me one of these of a different brand and it remembers where i set it even after being completely unplugged, so it's not like these devices can't have a type of memory to reserve settings. I'm wishing now I'd of research this before I bought it. Would not recommend if this issue would be a bother to you... otherwise leave your computer running all the time. Outside of that I guess it's ok, so I gave it 3 stars anyways as it does work good.

It's in the title. It broke as soon as it was connected and it was not worth the cost to ship it back to return it.

Controls the lights well, but every time you shut off or reboot your computer, it loses your settings for the lights and you have to change the mode again to what you want.

Turned my computer off when I plugged it in and didn’t even work at all.
