Pretty good quality for the price. I wish it took AA batteries instead of AAAs, but I can deal.
Two problems:
* The power button is on the bottom. This is ergonomically wrong, since it requires two hands to turn it on. It should be on the side, so it can be turned on and off with one hand...
...this is important because...
* There's a flashing mode that needs to be avoided, and you'll be pressing the power button a lot to turn it off. The speed of the flashing may be too fast for such a bright object, and may induce seizures.
