Review on Sumnacon 220 Degree Peephole Rotating Privacy Hardware by Andy Hearshman

Cheap. I opened the package and when I unscrewed the inner and outer part from each other, the lenses (a bit) fell to the ground. My dog immediately pounced on one and ran away with it. After catching them up and returning them, I tried returning the lenses but had no idea how they were doing. It seems that there were two convex lenses and one concave lens. No combination gives a clear picture. I have requested a replacement from Revain as I believe mine was defective as the lenses were not held in place. I got the second one, the lenses didn't fall out, but there's no clear picture either. IMHO, scrap. Keep searching.
