The pros: good brightness, I've seen and own much brighter, even for the size, good mode separation, good grip, looks nice, good button.

There are three serious addressable cons. 1: although AAs work, they are unreliable and difficult to use. Sometimes you get a selected brightness, sometimes the batter AA gets you just this minimal mode, even when it is fresh. Rechargeable NiMH batteries always go to the lower setting unless topped off.
Con 2; the light has a crazy U.I. although it is nice you may cycle through each mode and have memory for any one mode you want, there are no shortcuts. This means you must cycle through all levels to get to a desired output that isnt what you left it on. For instance, if you are on medium but want maximum you must go to low before you get it.
THE WORST PART IS: YOU MUST PASS THROUGH STROBE AND SOS TI GET TO OTHER MODES. thus if you are on low and require max, you have to strobe yourself first before you get turbo.

Turbo gets very hot but the trade off is you get a long use of turbo mode. You can indeed get instant strobe or turbo or low mode if you such want this ability. If you really want a flashlight that always comes on in one of these particular modes, it's easy to set it up that way and that's nice.

The cute holster is good quality. The anti reflective coating is good quality. The battery is a good but very long cell because of the charging. The lanyard is nice. Overall the flashlight is very nice quality. It gets 4 stars from a nice quality and seems good longevity. Loses the star from poor U I. And lacking AA full functionality. At least it always turns on with AA batteries. Don't by this to only use AAs, brighter more functional AA lights exist.
