I think the "You get what you pay for" is accurate. I had a BSA 6-24 that I paid $69 for on a Black Friday. About the same quality as a CVLife. While you could see, the edges were very blurry, tracking accuracy was iffy, and just didn't have the vertical range needed for an airgun. Admittedly I purchased just to see what a 6-24 could do, and it did that. I finally adjusted it so I could see, but anything over about 16x was useless. And, I shimmed the scope to get the elevation I needed.
By the way, I have another BSA scope that is phenomenal. I paid almost $300 for it, but it is a 3-14. Clear to the edge, tracks well, and sits on my Marauder.
22Plinkster did a torture video on a CVLife scope, pretty tough, but just not that good of quality glass. They work, but not as well as slightly higher end scopes.
If you are OK with poor quality glass, never move the cross hairs after zeroing, and are willing to shim, they do work.
