Only complaint I would have is ordered these twice now and both the ir control boxes that I received didn't work due to a bad soldering job

You have to either suck the solder or cut it again shorter.- when you try soldering the material it burns and gets all nasty

the good parts of bad strings of LEDs are soldered together to make up the string and they simply fall apart

The remote unit ir receiver is very delicate, be gentle with it so the wires dont break or the solder let loose.

Bought it last minute due to not having party stores around me with any type of modern décor or ideas and came in day of my daughters birthday and I couldn't even use it.
