"So, My first magnifier was the one by UTG and it was awesome. it was crystal clear, the flip to side feature like in COD, and good rubberized nubs to give you a good grip, and was only $70 dollars. I put it on my Acr and it was perfect. And about a week ago I bought this because it was only $50 dollars, expecting the same results, I realized I've been ripped off. It zoomed only about 1 foot and constantly foged. AND it was a lot smaller, and it is only quick detach, which means it either stays zoomed in on your gun, and to change it you have to pull it off and hold on to it, and when you want to zoom in again, you got to slide it back on and adjust it. On the UTG there was a focus mechanism that helped a lot.so sign on this thing either. So take my advise and save your money and just buy another optic or something."
