I took this string to put in my room. I mainly use the USB port or the radio. Both work perfectly. The sound volume may drop very low and go very high. Some comments put a damper on the remote control. It is actually quite small, finally to go with a MICRO chain, it would be strange to have a 30 cm remote control! Personally, despite my fat fingers, I find it very well. I have not tested the CD player function, it is not made for that home. Installed above my closet, I do not see myself climbing a ladder at each change of disc! In short, a great product that I recommend, and fully satisfied my expectations
