Xtreme USB Powered Sound Reactive LED Light Strip with 8 Unique Colors, 8 Color Changing Modes, Preinstalled Adhesive Back and Included IR Remote – 6.6ft

Mine arrived with about a foot of the strip not working. Amazon gave me a credit so I kept them since the end didn't really matter to me. Sticky tape is OK. Make sure the surface you're putting them on is clean and flat. Glass and plastic would be best. Lights are bright. I have them on a static color so the sound part didn't matter to me much, but they are very reactive.

I bought three of these at the same time, and using them under the cabinets in our kitchen. The problem is that I think they've either been in the package too long, or perhaps exposed to something that has broken down the material. The backing should be sticky but it doesn't stick well. The clear rubber waterproof surface is very sticky, and shouldn't be based on other similar products I've purchased. They are all of various lengths, which is odd because they should all be the same length. About 24 hours is all you'll get before they fall off the surface of whatever you've attached them to. But they're cheap!!

There is literally nothing "sound reactive" about this device. It's four buttons that are supposed to react to sound literally just go between different fade setting, and the fourth one doesn't even work. Literally returning it right after testing it and writing this because it was a complete waste of time and money. 0/10. Would NOT recommend.

I purchased this exact item in a local store. The colors are pretty and bright. I plan to use them as solid lights, which is good because the music sync part doesn't work right. They do flicker when there is sound, but it doesn't noticeably correspond with the music. So if you want something to react to music I'd choose a different brand. For USB powered solid lights these work fine. I'm using these at my camp site - I bought three strips so I can display red, white and blue for patriotic holidays, and red & green for Christmas. They use very little power so I can go off-grid with these by using a USB power bank.

Not all the light colors turn on. The different cycles on fade, sound or jump are all the same.

The media could not be loaded. What a waste of time, money and energy. To begin with they do not respond to the beat of music. That they flash and turn different colors (which I dislike) because I would like to choose the color of my choice. I was bothered that I couldn't even select what color these lights should flash to. Instead, it turns on preprogrammed which are like the colors of the flag to another country. Honestly, it was not worth my time to return but I will just stick to the lighting I already have in my room.

Great but when I play the music it doesn’t work

It randomly flickers like a bulb that’s dying. It simply starts and stops to sound. Garbage!
