exhaust nuts

I was wondering if anyone has experience of using these alternative exhaust nuts which are available from motorworks. One of mine is completely shot and i'm considering this as an alternative.

Looks a nice alternative to whizzing the heads off for a thread rebuild. They've been around a while so obviously do the job
