"This sight is amazing. The dot is tiny, but pretty bright; you won't lose it during a game. The rails are actually longer than they look online, so they can easily fit a flashlight or laser. The button used to turn on the red dot is also used to turn it off; other sights that I've handled don't turn off with a button, but instead require you to pop the battery out and put it back in. However, I do have some problems with it.
1. The cap for the horizontal windage dial won't screw off, so I can adjust it.
2. It didn't include any instructions or anything similar, so I had to just figure things out on my own.
3. The dot is a little blurry when you first turn it on, but it corrects itself after a minute or two.
I honestly don't think that the cons outweigh the pros, and this is an AMAZING sight for the price."
