For crimping battery cables lugs this tool really kicks butt. I was sort of scared to spend the money first since I didn't have that many things to crimp. But I do know that loose wire connections of the fastest way to hell with a fire. I also used a anticorrosion cream. Once this hydraulic tool made the crimps I could not pull them apart even if my life had dependent on it.
I'm not sure but I think last week it was $10 cheaper.
This thing works great all the way down to 1/0 wire battery lugs.
