Three words, It's really BRIGHT!

The main 3 positives are: 1 extremely bright and wide flood, with a very wide spot and a flood that reaches the tree branches or ceiling above you and the tree roots or floor right in front of your feet, for superior outdoor and indoor illumination.
2 the nice quality. The build quality leaves little to be desired. Nice tight threading, good switch etc. The LEDs are not perfectly aligned but it is very close. Feels like a good watch. Feels wonderful in the hand, smooth and refined but still grippy enough the knurling won't let you drop it.
3 the size is very good. Other lights that are brighter (only 2 production lights are brighter, with a 3rd that ties it) are much much larger. This is so tiny I can carry it all day. It really is smaller than a pop can, shorter by a hair, with a thinner body, the bezel is identical in size to a pop cans' body, and the rest is smaller. I thought the picture Acebeam has could be fake, but it isn't, the flashlight is as small as the pictures suggest. Not super light, but not too heavy either.

A couple expected negatives. The lowest mode is 200 lumens which could be lower. The strobe is only 4k lumens , the highest mode doesn't come on with 4 clicks you have to pause after it in turbo. No momentary. These things combined makes it a poor choice for tactical or self defense use. The flood is awesome, but limits the practical use of throw to about 100 meters, not 300+. The handle requires tightening by driver. There is no real roll stop. Only takes button top and really prefers protected cells for length and fit.

To sum it up I recommend it for bright flood and wide floody light in small package.
