I received this from tryit sampling. I really liked these lights at first. They were easy to assemble with lots of coloring options. However, the battery doesn't seem to last long and at one point the color was stuck on red and I couldn't turn them off unless I took out the battery. They would come back on correctly if I put the battery back in but that didn't last long and they wouldn't turn off again with the off switch and I would have to repeat taking the battery out again.
