I have one. When it works, it's great. When a primer goes sideways between the tube and adaptor, it's a pain. Or when one hangs up, sideways, before entering the adaptor.
I had to use a round file to smooth off some edges.
It's spectacularly unreliable with Federal SR primers, but seems to be working fairly well with Winchester SPs.
Takes about 30 seconds to fill a tube. This is about four times faster than manually picking them off a primer tray.
Scuttlebutt on other forums suggests that quality control is hit-and-miss.
I don't know where to get one in Canada. Ordered mine up from the states.
I will eventualy get a Dillon RF-100 and pass the vibra-prime along to someone else.
