I find this crossfield scope to be a excellent product. My only complaint is the rear scope cover won't stay on once the focus ring is backed out for my eyesight. It's to shallow. I believe I have that problem solved with purchase of Vortex 40mm front scope cover (defender) for rear of huskemaw. It's at least twice as deep. Not a perfect fit but will work. Other then that I plan on shortly buying a second crossfield. All the other Chinese and American made scopes are to busy. Customer service was absolutely fantastic with a small issue I had with missing screw for zero stop ring. I also had a custom turret made for my excalibur crossbow speed and was dead on from 20 to 50 yards. Thanks Rob Gee
