I purchased 2 of these, and immediately noticed that one gave off a bright white light, and the other a warmer white. Also, despite being charged the same, one only works for about 30 min, while the other lasts several hours. What a disappointment.  So I would give 5 stars to the one that holds its charge, and 1 start to the other... so settling on 2 stars because one is not great, but also, they should not be different.
