Well, it's not a scope, and people that are complaining about no magnification and it being a "cartoon scope" need to read the fine print... That's how you get screwed over. But seriously this is a great scope. It does what you pay for: sit upon the top of your gun and sight your targets like a good little scope. Don't expect top of the line quality if you're only going to spend twenty five dollars.
-Does what you pay for and does it well
-Adaptable; the mount allows it to be placed most anywhere on your gun, especially if you have an M4 with RIS system.
-Is visually appealing, and I would recommend it to any friend who didn't have it already!
-In agreement with previous critics, it is difficult to sight it properly, due to the fact that the knobs are difficult to turn when you initially install the sight. Also, if the dot is not moving when you turn the knob, try turning the knob the opposite way. It worked well when I tried it.
-Scope covers could use some super glue or something of that nature, due to the fact that they slide of fairly easily.
-Other than that, there is nothing. An almost perfect sight.
