To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Also, battery life is poor. After about 1 or 2 hours, starts dimming or even entirely dies out. Also, the provided USB cable didn't fit well (micro-B I think), but no big deal since I had a extra bunch of these from previous devices anyway. Also, everything (entire instructions booklet) is entirely in Chinese but this shouldn't really matter since there isn't much to be figured out (lamp with one button--click 3 times to cycle through 3 modes).
