Review for model:

Very good product but does not fit Glock 19 Gen 4. The guy who was advising me, a complete layman, made a mistake. It happens. The collimator itself looks very good.

Review for model:

Collimator is quite good, 1 spare battery is a nice addition. Adjusting the dot is not a problem. In my unit, it's slightly blurry, but it's not an issue. I think I'll fine-tune this detail. On a very sunny day, the dot is invisible, but I still recommend this device.

Great little collimator, good vivid image, and a nice dot. I recommend it!

I bought it to use on the Zoraki HP-01 air pistol but not good for precise shooting. The iron sight is much more accurate, I had to send it back.

So far it holds up on the gas Glock :)

I ordered a different one and this one arrived. It’s fine and I didn’t return it....

A very nice collimator as an additional sight, for example on a scope, I recommend it.

Good small collimator, perfect as an additional sight, e.g. on an optical sight. I recommend it.

Good small collimator, ideal for mounting at a 45-degree angle or above a scope.

It's good enough for quick shooting outdoors. Unfortunately, it is not suitable for precise target shooting indoors, where the aiming point is surrounded by numerous and strong ghosts. With the Zorki Ultra air pistol, at a distance of 25 meters outdoors, all 20 shots fit easily within the field of the 9-ring target (diameter 10 cm, i.e. ~14 MOA). The collimator was only roughly tuned with shots indoors at a distance of 5 meters.
