Things I liked: crystal clear,

Things I would have changed: the cover over the parallax adjustment is just plain stupid unless you shoot at the same distance all the time.

What others should know: great scope

Things I liked: I like the clarity at all levels of magnification. The illuminated cross hairs are nice, but the cross hairs have an illuminated ring around them. This may bother some people, but not me. I find it easier to acquire my target faster with the illuminated ring around the cross-hairs. This scope is well built, it should last for years. I mounted it on my Kral Puncher Breaker in 25 caliber. I like the location of the red-green illumination on/off buttons, and that it has three levels of brightness.

Things I would have changed: I would change the way that the sunshield mounts to the objective lens of the scope. I received the optional UTG sunshield as a gift, and with it installed, the parallax adjustment cannot be rotated. Either make the threaded portion of the sunshade a little longer or make the internal threads on the objective lens a little less deep. This is the only complaint I have with this scope.

What others should know: This is a great scope overall, it is very well built and the adjustments are very positive. The red/green illuminated cross-hairs are nice and clear, and the scope takes a very common battery, a 2032 button battery. The only problem I has with this scope was with the attachment of the optional sunshield, which I did not need, even in bright sunlight. Definately buy this scope, it is one of the best ones I have used for under $100.00

Things I liked: I felt that this scope was the most accurate of the scopes I owned, so it deserved a spot on my RWS Diana 460. It was deadly accurate for getting rid of ground hogs. However, this review is mostly about service. This year the scope needed to be re-centered and the windage adjustment wasn't working. There was no clicking sound when I turned the knob. I went to Pyramyd Air looking for a replacement and saw that Leapers scopes had lifetime warranty. I went on line and filled in the warranty form. Within hours I received an email with an RMA number & instructions to return it. The person I worked with was Ryan Brown and he was very flexible. I sent the scope in and it was fixed & returned in about a week. Mr. Brown explained the problem (loose turret locking screw) and sent me instructions on how to check for the problem and fix it complete with a picture.

Things I would have changed: Include the manual to detect loose turret screws and how to tighten them.

What others should know: Kudos to Pyramyd Air as well. I purchased the scope over 5 years ago and their order history only included the last 2 years. I sent a request for a copy of the invoice for this scope and they identified it based on my description (no model number was on the scope) and sent me a copy of the invoice. Overall, this has been a good experience and I will not hesitate to buy another Leapers scope.
