I was over the moon when I saw these lights that could run off a usb box...now I regret my purchase. They are a waste of money and time. It took me ages to thread them carefully through the mirror I was using them on. I modified the mirror so the wire exited the back and there was a concealed shelf for the usb box. It looked fantastic and the different modes are ideal for any mood. The length is generous enough to make a nice show for any project. I was so happy it was appeaeing I had found the solution to my battery issues regarding lights. It was going to save loads of time.
After a few evenings I noticed I was having to reconnect the usb box to get the lights to turn on again. The output was just right for the lights and wasn't too much or too little. I was confused then I bumped the mirror after fiddling with the andusb box again, they turned off again.
The wires are over sensitive or there's a flaw in the sets I have. Like there's a connection loose.
Now I have to unthread the lights. It's a waste of my time and money. They are highly sensitive to being manipulated and turn off so easily. These lights have a serious design flaw.
I don't recommend these unless the company can sort out the kinks.
Hope it helps someone else not waste their time.
