I haven't used them, but there's a thread over at ttips talking about these kind of inserts...

I used some similar, much lower quality though, inserts and they have worked great. I am using salomon downhill bindings and the inserts hold them extremely well. One thing to note is that it took a lot of effort to mount the inserts compared with just mounting a pair of bindings using the normal way.
