I've had crap tools from Screwyou to. Some wire strippers - they
replaced them once another crap pair so I complained again and bought
some better ones. Got refund but they didn't want me to return them
which means that they knew they were crap. I gave them away (2 pairs)
as christmas presents.
Another tool was wire cutters - good quality but badly adjusted with
signs of having been hammered a bit to tighten them up - in other
words someone elses returns. OK now i've hammered them a bit more.
So watch out Caveat emptor etc.

cheers

Jacob
