Rated 4 out of 5 by from Great light, but pricy. This is a great versatile little light. It is extremely bright and the dial ring for the different modes is very easy to use. If I had to knock the design for anything, it would be that there may be one more function than necessary on the dial, but perhaps someone actually uses the beacon (about one flash per second). Best part about this light, and the reason I chose it over the SRT5 was the battery versatility. They advertise the ability to use 1xCR123 (3v) or 1xAA (1.5v), but you can also use a 14500 rechargeable battery, which is a 3.7v that is the same size as a AA. This gives the SRT5 a brilliant amount of light in a very compact design and the ability to use AA's in a pinch. Easy to keep on the belt, in a bag, or in a pocket without being obtrusive. Design seems to be pretty rock solid. I can see this thing outlasting any light I've ever, or will ever own. The downside is the price. You can get other lights around the same size, with similar brightness for less, but I really wanted the extra functionality and infinitely adjustable brightness.

Rated 1 out of 5 by from Not Good! better flashlights for that price. Battery life is terrible and the on/off switch is cheap.
