I have a set of two similar, maybe even from the same manufacturer. They look the same as those in that auction. I bought them from MicroTools Europe (Germany), and paid significantly more than the current auction price...
Tools are OK, although I suspect those from SK Grimes might be of better quality.
I've used them several times, and have no complaints. Maybe not for professional use (if you open lenses all day long, and do that for a living), but I'd say those should be OK for an occasional tinkerer.
HTH,
Denis
