"Used with 70mm hole saw for soffits. Little bit of play when put together which is why a star down. Maybe it is meant to be this way, but as there were no instructions with it I wouldn't know -Took 10 minutes just to figure out how to attach the darned things together!
Anyway, it did the job and looks well made. I now have three of these things as my other two (not from Screwfix) did not fit the 70mm and each one operates a different way. Why can't these things be standard?"
