Review for model:

Collimator with quick mounting, quite high, but that’s exactly what I needed. Large adjustment range vertically and horizontally. Quite nice build quality.

The instructions are unclear, I have no idea how to adjust, for example, the brightness, and there is not a word about it in the manual or on partner websites. The dot is blurry and you can't see the target very clearly. The only positive aspects are the build quality and the type of mounting.

Very nice sight, I didn't expect it to be so good. Only one point to calibrate, but otherwise I'm very satisfied. It's precise and especially looks nice, a bigger collimator does the job great on a rifle instead of a small one. I recommend it; for me, green is suitable for daytime and red for the evening.

Super satisfied. At first, straight out of the box, the dot was a bit blurry, but after a minute it worked perfectly. I played in very heavy rain, and it worked very well: before, during, and after.

For this price, it's great. The only thing to consider is its height. For airsoft, when you have a stalker on, aiming might be a bit inconvenient, and it would be more comfortable if it were higher or mounted on a rail riser.

Very nice and compact collimator, I recommend it.

Nice little collimator with quick mounting. Good enough for a first gun ;)

At this price I didn’t expect miracles, but it’s really great and clear.

I recommend it, I use it with my MP5!

Nice little collimator, I use it with an MP5 from Cyma. I recommend it.

Best in this price range!

Good quality, fast delivery.

For this price, it could be better made.

A lightweight collimator, easy to adjust. Ideal for airsoft.

Very nice little collimator, at the strongest setting it shines very brightly so even during the day there won’t be a problem.
