Very nice little collimator, just right for mounting somewhere on the side of a rifle. The whole thing is almost unnoticeable after mounting. The dot is not super precise, but that's not what the collimator is for. The build quality is very good.

Very solidly made collimator. Holds zero well. 10-step brightness adjustment and smooth vertical and horizontal adjustment work very well. Mounted as an auxiliary on an angled mount, it performs great. Automatic shut-off when the cover is put on works, so the battery lasts a long time. In this price range, I highly recommend it.

I am 100% satisfied, that's exactly what I was looking for. Mounted on SpecnaArms SA-BO2. Exactly on the Monolith Theta Optics closed collimator ...available in the store. It's a bit strange that the method for turning it on and off was not described in the manual.
-
The dot is terribly blurry, in my unit it was not possible to change the brightness or turn it off, I'm returning it tomorrow, but the collimator itself is nice and good quality.

Very good Reflex, after slightly raising the RIS rail on the JG MP5 it fits perfectly. The workmanship seems very solid, and the lens nicely reflects light. The only remark is the battery installation, for which you have to unscrew the sight from the rail.

A solid and very well made collimator. Used in various conditions and fulfilled its tasks. I am very pleased with the purchase. Worth its price. I recommend it.
-
Very nice mini collimator. Fits perfectly to the Umarex Tornado revolver. The dot is clearly visible, 10 levels of brightness for it. For those who don't know - to completely turn off the collimator you need to simultaneously press and hold the + and - buttons on both sides of the device for a few seconds, which are used to adjust the brightness of the aiming dot. To sum up, I definitely recommend it.

Great mini collimator, on a sunny day the dot is very visible, in my unit the dot is very evenly focused. The price is very affordable, well made, big plus for the rubber cover on the collimator.

For this price, this collimator should be considered good. The dot is quite precise. You just need to solve the puzzle of turning it off to zero. Apart from that, I recommend it to airgun users.

Good collimator for little money. Unfortunately, I returned it because it was not really possible to mount it, as the Diana has an 11mm rail and the adapter raised the collimator too high. Changing the battery is very inconvenient, you have to disassemble the collimator, so you have to re-zero it again.

The collimator is of very good quality, the dot is precise, small, slightly blurred on the side, but it does not affect aiming. Changing the battery is very difficult because you have to unscrew the collimator. Unfortunately, I have to return the collimator because it does not fit my rail, I have the old RIS type with a different slot spacing.
-
A good quality collimator at a reasonable price. High resistance to shocks and water resistance are a plus. The battery lasts quite a long time. I can recommend it for testing.
