I have had mine for over a year now. My thoughts and experiences...
The optic would not focus correctly till I torqued down the loctited ring that holds the magnification settings on top. Once I did that, it got better and I could focus it adequately. That also made the magnification off because the rubber ring with magnification levels is glued the to ring I just turned. So I had to lift the rubber ring by separating its glue and rotating it back to the correct position.
I also had the focus tight one way with backlash the other way that makes the optic neay impossible to focus because of the super sensitive focus from the coarse threads and slop that allows the focus to dtift. The Oring trick helped a ton with the inadvertent movement, but nothing will help the lack of a fine focus knob snd coarse threaded focus.
The rails work great, but they are cheap with cheap screws and tend to back out. You really need loctite and torque. It needs a new cover so you can keep things on the rails. The factory cover is worthless. Will get a Triad eventually. The eyepiece is a different size than the Leupold MK4 / M151 it tries to copy, so things like a Badger SNAP or other Leupold accessories wont fit.
Its a good but finiky low end spotter. Not garbage, but not great optical quality either and not very user friendly. I wish there was something about 50-70% more expensive with better optical quality, build quality, and user friendliness that also had coatings that were NV friendly, but there is not.
Even the Leupold GR HD which is better optically than the standard Leupold MK4 kills NV transmission with its coatings.
