I have had two of their higher end and still have one of them. I have the 10X 50mm on my 243. It is a good scope, but the glass is not comparible to Nikon, Leupold or others of that caliber. It is works well with the 100-200 yd hunting range that my wife hunts. I also had one on my 220, it was a 24X and it was anice scope for the price, I replaced it with a leupold just my preference as I was looking to air that gun out and I was able to do the upgrade. The higher end are Ok scopes, I have bought a couple of the lower end for a couple of 22's for squirrels, they weren't good at all. Took the first one back and got another one and it too wouldn't hold a zero. I don't use these anymore.
