I've owned this optic on a Huben K1 since last October. I have had zero issues with the scope. I have been using it a lot lately and really like it.
The field of view is quite large for 10x because of eye placement against the rubber cup. If there is a downside it is that I am a hunter and I use 4-8x on most of my rimfires. 10x is a lot more of a challenge to hold steady so a nice rest is very helpful.
The focus knob works great and requires very tiny adjustment to change focus. Best of all the glass is super clear. Best $500 I've ever spent on an optic!
