“The crimper only works for the thin copper lugs it will not work with the heavy duty thick copper ones if you try to crimp a 1/0 on the 1/0 die it just completely mangles the lug then you had to spend 15 minutes with a Dremel and a cut off wheel and a pair of new nose pliers and a hammer and chisel try saving the wire that you stripped back because you can't compromise anymore length of wire to be cut back that sucked no matter how you try to crimp it different”
