The light show is great!! However: First: No where in the information on-line does it say it is for indoor use only! That is a critical omission! Second: The instructions say to use it for no more than two continuous hours! Again a critical issue. Third: The instructions are really bad!! They must have been written by a Chinese and translated by a non-English speaker who was marginal in Chinese. Really, how hard is it to provide a good set of instructions? But, the lights are good.
