I've got this jointer.
it works fine, everything lines up as it should and the fence sits parallel to the blade (fairly sure it can be adjusted).
my only issue is the slide mechanism on the fence can be a pain as it's a small cog on one side so it can twist the fence and stop it moving when adjusting occasionally, nothing major just an annoyance at times when I'm rushing, once the fence is locked down for cutting it's perfect.
I'd take those 1 star reviews with a pinch of salt myself and suggest that some of the complaints are from lack of correct setup on their part not the tools.
