I bought 2 of these to install on some older doors. They look decent. Instructions are poor. For example there are parts shipped loose that aren't listed anywhere, but you need to put them together. I have assembled knobs to doors before or I would have had a difficult time. The real issue though is one of the two is defective, the hidden flange for the screw heads is not lined up properly with the access holes for the screws. You can only get about half the screw head engaged, if you tighten it, it falls apart. It's a simple hour or two job turned into a multi day event. I'd prefer to spend more for better quality.
