Seriously flawed - Lightstar Colorado Flashlight, 580 Lumens, Black/Gray

The flashlight works ok but its main feature, multi-mode brightness, is extremely difficult to use. You can spend many frustrating minutes trying to switch among brightness modes and, unless you want to devote the better part of your life to practicing this interesting activity, seldom get it right. If I had it to do over I'd take a pass on this product.
