I bought this for use on a .22 handgun... I have two Burris Fastfire III's on bigger guns, but I wanted to try something cheaper on a .22 plinker.
This is the best Fastfire clone that I could find, mainly due to the momentary switch and adjustable brightness levels. The models with a cheap physical on/off switch are more likely to fail in my opinion.
The overall quality is nowhere near the Burris offering and I would probably not trust it to last on a larger caliber weapon... but at half the price, I think it is a good budget option for a light use range weapon.
Pros: Price, momentary switch, adjustable brightness
Cons: Cheap zero adjustments
