I like it a lot. Great for short range shooting and accurate at 100 yards on the 4x magnification setting. It adds weight but is nice and clear. Great scope for the money. I've only had red dots until I got this so setting it up for the proper eye relief took some playing around with. I'm very happy with it and my kids are happy I finally got some magnified glass.
I am thinking about putting it on my 15-22 to see how I like that set up also.
