Things I liked: When I was deciding to purchase this scope, I was worried that it didn't have an ocular lens adjustment as stated on one of the other reviews but it had everything else I was looking for so I purchased it. I was delightfully surprised, there IS a ocular lens adjustment...just pull the dust cover off to adjust. Awesome product. I've got this on my Beemer R10 (old but quite powerful) rated at 900fps. This gun does vibrate and the scope holds it's zero to the T. Scope covers are firm and very predictable, turrets are decisive AND re-adjustable, even at 12x zoom the optics are clear from edge to edge. With all the quality and DURABILITY of this scope, I would expect to pay quite a bit more. Amazing that this works with spring air guns as well as regular fire arms whereas scopes designed for regular firearms would get destroyed on spring air guns...and cost a hell of a lot more. Illuminated reticle is fun but I don't hunt or plink in the wee hours so I just leave the battery out. During regular daylight hours, the unlit reticle is crisp and jumps out at you. I would recommend this product wholeheartedly but be prepared to spend a few bucks on mounts if you don't have weaver rails. Other than that...it's perfect!!!!
Things I would have changed: Choice of mounting rings.
