I think they are total crap.. thats just my opinion though.., very brittle plastic frame ,you cant see through the screen,they are not cricket proof like they claimed when I bought the one I had .
I guess they wouldent make a bad sunning cage But IMO you can make a much better sunning cage from 1/2"x1" PVC coated wire and j clips, that will last much longer for half the cost or less
