Not bright, badly soldered (loose connection in blue led) and the power cable is very short. I cannot recommend this quality.
Very disappointed. The led strip itself is OK, it the controller is garbage. I got it to work using the Tuya app, but after it recommended to download a firmware update, it simply stopped working!! It only blinks slowly and can't be recognized by any apps on my network. Be careful, if you buy it, don't update its firmware!
