Totally awesome quality. Solid, precision made, just like Leupold scopes. Two complaints are 1) there were no instructions,so I didn't know my rubber eyepiece ring unscrews from the scope and is replaced by the flip cover. Called tech support and they explained it so no problem, just a minor inconvenience that could have been avoided; 2) they covers don't align with the hing centered on top when fully screwed in. They can be backed off to your desired alignment, but I would prefer they line up when fully screwed in. These are pricey but are solid aluminum, lightweight, strong, use double o-rings, and I think will provide optimal protection. A sensible purchase for a scope worth this level of protection.
Pros: high quality
Cons: expensive, no instructions
