If any one is looking for an in-expensive static bench prime this is the one. I've just bought one for under £32 and is very good to use.
It is very simple, positive primer seating, and very easy to use. It is made from pressed steel(?) and plastic primer hopper
You tip the primers on to the hopper and shake it until they are all the right up, close it in half, push it in place on the primer unit and away you go.
It take standard primer shell holder from a hand primer.
Well worth it money.
