Great design and build quality but a bit too small in diameter for my work bench.
I bought these to use with my Ramia work bench and to just putz around with some woodworking projects.  The holdfasts came in fast and a bit earlier than advertised.  I had lost them inside some boxes and by the time i found them it was already past the return time.  I had found them and wanted to use them, but they were big enough in diameter to be useful with my work bench.  They can be used but they do not hold fast and allow the work piece to work loose.  I just keep them around, they are now really big paper weights.  I will try to find a way make them useful, perhaps putting some leather in the workbench holes to see if that will keep them more secure and lock down.
