I woulda bought the Bostich, but my brother was buying, so.....did two roofs with it and it lived. A bit fussy on nail coil quality to begin with, jammed frequently , but once it was figured out that it wanted nicely coiled nails it went away. PErhaps it was happenstance.
Didn't like the variance in depth, but I think that is operator related.
Length of nail adjustment is hokey
likes to be well oiled
