This crimper works well. I was hoping it would have the awg sizes printed on the dies, but it only has the mm sizes printed on the dies. It works very well, just takes a little more time to figure out which die to use for bigger awg cables (1/0-4/0) I have a smaller hydraulic crimper, so only bought this one to use for the bigger sizes.
Definitely put the heat shrink on before you crimp on the lug or terminal. Overall works well!
