Great thing, I'm pleasantly surprised. For little money, it does its job. Looks great on the Sig Sauer MPX, the red dot is clear, the power has 5 levels—highly recommend.

A basic collimator, 2 colors to choose from, looks quite okay with the AK1 from Crosman, adjustment is relatively simple, but as in other reviews, a crosshair would work better here instead of a dot which is a bit too large for precise shooting

The product matches the description. The quality compared to the price is very good. It's a pity there's no anti-reflective coating, but the price explains it. The collimator is well made. The dots are clearly visible. I recommend it, it's OK.

In my opinion, a great red dot sight for airsoft games. The sight itself is well adjustable, but instead of a dot, I would prefer a crosshair, which personally makes it easier for me to shoot. I’m not deducting stars for this because everyone knows what they’re buying and I recommend the product itself.

Good adjustment, solid workmanship, everything is okay

The product gets a solid 4 stars from me. It's easy to adjust. It has a lot of functions. I take off one star for the size; I think 1x30 is good. Also, a crosshair instead of a dot would be better. But overall, I recommend it.

Now, my friends, finally all my shots are hitting the black field on the target. Great help for less experienced shooters. I recommend it, especially since it's inexpensive.

Great collimator at a good price

Awesome sight, good and quick adjustment, large range of dot size. I recommend it

The collimator is really well made, firstly it's metal, secondly you can choose the color and intensity of the dot (green or red). Big plus for the battery included in the set. It's very easy to adjust, definitely worth recommending.

The collimator is well made, solid for this price. I recommend it.

Very nice collimator but I think it needs to be raised, at least for me :D I can confidently recommend it for this money.

The collimator is just right for beginners. I recommend it

The collimator is quite heavy, but it does its job. 2 colors to choose depending on the terrain, works well.

A good quality collimator, but I would definitely choose a 30 focal light.
