All reviews that says coasters are junk is 100% accurate. Here's what to do when you get these lights: save the lights and throw the racks in the trash just before they fall and 1) smash your new lights, 2) hurt you or someone if they fall, 3) you make you look totally unprofessional if you fall at exactly the wrong time. The overall quality of the lights themselves is pretty good. The brightness and color controls work great and I haven't had any issues with flickering or anything like that.
