I have been using a Kreg system for about a year. It does not have
much application in my work but it does come in handy every now and
then for bracing or support.
I do find that *sometimes* the pocket-holed piece will jump forward
just slightly when cranking down the screws.
It is minor but if I were using it for finer work it would be a
problem. I have tried a number of solutions from the manual but I
still seem to get this from time to time.
