Buyers Beware!

The tools look nice, with a good finish also looks strong unfortunately the augers were a bit too big on the bottom which it makes the whole thing un-usable, I had to return them.

you might want to pay a little more elsewhere

on first look they seemed ok, but then I saw the bent drill bit that wouldn't spin when set flush to the chisel. now a bit dis-heartened to look too closely at the rest.
