||I purchased two of these sights, as they looked to be the best on the market - i was right.
These dot sights are excellent. As mentioned in the description there are three light intensity levels and four different sights to choose from, depending on your preference.
The sight works by projecting the image (e.g. dot) onto a mirror (the screen part you look through) which then reflects back at you. Whilst a lot more lenient then a high powered scope, you do still have to be lined up with the sight to properly look down it.
It also means that the main part of the sight is a mirror, so in high light CQB situations it is even more important to line up the sight properly.
It is worth noting wearing mesh goggles does cause a slight refraction when looking down the sight, but this is very minimal.
Also, as i live in the U.K. i did not get any batteries with mine, and had to buy them at approx £3 each.
Lastly, a screen such as this one (http://www.airsoftpost.com/product_info.php?cPath=32_177&am-
p;products_id=30845) would be a good investment, just for piece of mind.
I personally have fixed this to my G36C, and had to remove the rear iron sights so i could effectively switch between aiming patterns and for optimum visuals.
Overall, and excellent sight that i would recommend.
