The collimator is quite nice, it's my first one. As others have written, due to the darkened glass, you can't see anything when it gets dark and when the sun is shining behind you. However, for indoor use, it's first class. The sight is clear and you can change the color.

As for sharpness, I have no complaints, the circle really looks nice but that's where the positives end for me. The laser brightness is very weak, so in the light it sometimes seems the collimator is discharged even at the highest brightness. The lens is slightly darkened, although it doesn't seem like much, but when I started playing airsoft and shooting with both eyes open, I wasn't very good at CQB in dark rooms - it became a nightmare. Made of metal - but only on the outside, everything else is plastic. After a month *crack* suddenly four corners, the lens cracked despite the optic cover, I have no idea what happened, I don't throw my gun around, a BB couldn't have hit it, but who will believe me when I try to explain ... Below are pictures, quality is poor because they were taken in the field.

Great aiming point, it's large and clear. The collimator itself is solidly made. I bought it a second time and can recommend it to anyone who wants a good collimator at a good price. :)

Very nice, but if someone wants this collimator, it's only good for milsim because it's not suitable for darker areas due to the tinted glass; otherwise, it's perfect. The set does not include instructions, so for batteries: the minus side goes on the right, and the plus side on the left.

Great sight for a good price, clearly visible even on a sunny day, but it doesn't work so well on dark days because of the slightly darkened lens.

Presents and works decently for this price, although the laser indicator could be a bit better made. It's also very bright, even on bright days, but not so good on dark days because of the slightly darkened lens.

Review for model:

The holographic sight replica (holo) is an excellent choice - excellent quality, affordable price, comfortable and precise aiming, and solid construction.

Very good sight. Slightly darkened, which makes it a bit harder to use when it's dark, but only slightly. I recommend it.

Product as described. I recommend it.

Great collimator, good light adjustment, image does not blur even after mounting a cover, clear aiming point even in minimal light. Minus: the batteries were dead.

Great sight at a good price, it's clearly visible even on a sunny day.

The sight has a dark coating. It is useful on sunny days, but on more cloudy ones it can be a hindrance. The ability to choose between two illumination colors (red, green) and adjust their intensity.

Very good holograph replica, I recommend it.

Good sight.

Very good sight.
