Super overpriced for what they are. Flimsy. Coulda built these with a metal rod and some LEDs and a microcontroller in like an hour for like 40 bucks. Instructions for the remote operation are very poorly translated. Instructions for assembly fully skip a necessary step where you have to cut plastic off a wire inside the base or it won't fit together. And who wants to keep track of yet another LED remote anyway? The remote is battery operated, not rechargeable. Nothing about the operation is intuitive. Not my favorite purchase.
