Review on KOTTO Battery Cable Lug Crimper Tool 6-50Mm², Wire Crimping Tool, Pliers For Crimping Wire Cable With Cable Cutter For 10,8,6,4,2 And 1/0 AWG Wire Cable Cutting And Crimper With Storage Bag by Nick Nunez

I got my job done for about $50 in parts (including this kit) when the plumber wanted $600. The tools worked just fine. I did pinch my hand with the cutter the first time I used it. (water spraying out made me rush) The crimper was a little tricky in some positions (working overhead) but it was doable. I recommend doing a couple of practice crimps before you do your final stuff. Oh, and someone in the reviews here said you could use the crimper to remove old crimps. I tried their method and couldn't get it to work. I ended up using some 8" bolt cutters. They took a couple of passes, but did what was needed. There are some videos on youtube of how to release the crimps with a flathead screwdriver, but it looked like a PITA.
