"So far I am happy with this light. I got the tan one for cheap so I thought I would try it out. The finish is very nice. There is no play in the tail switch and it has a nice quick press. You can press the middle button lightly to momentarily turn on the full brightness. Both paddles turn on the strobe momentarily. Click the center button to turn on full brightness the press a paddle to toggle from high to low brightness or hold the paddle to turn on strobe. This setup is everything I want in a weapon light or tactical light. Simple to use, no need for 10 levels of brightness and have to cycle thru everything. I have this mounted on a real steel ar pistol using a UTG keymod offset mount. It fits very close to the rail. I don't even need a pressure switch as I can easily reach the tail cap with my support hand. My only complaint is a bit of machining burs on the bezel but I can easily fix that. I hope it holds up to real use because I am impressed with this light for the price. I am using a 18650 samsung 25R battery to power it.
