From Ben in Ohio:
This monocular in my opinion, after having owned it several years, is not anywhere near worth its asking price. It is good, but not great. Pros: lightweight, relatively sharp resolution edge to edge, durable and compact. Cons: very slow focus, have to twist it many times to go from far to close focus, I usually had to start twisting before I brought it up to my eye and keep twisting afterwards. Not even close to having its purported eye relief, I couldn't get satisfactory field of view with glasses on, so it was difficult to get on a target. The lubrication for the focus would leak out a bit around the edge of the eyepiece lens, messy. Not very bright or color rich view even in good lighting (compared to my new leica monovid). Not waterproof. So, this little guy has a lot of room for improvement. My main complaint was lack of eye relief.
