I have run several thousand feet through this tool and it is great once you get it dialed in. If you are switching from one size wire to another it takes minimal time once you understand how the machine operates. The only issue I had was in the beginning the wire kept going been the blade and chuck. I found that bringing both chucks in a close as possible fixed the issue. After that fix, all of the adjustments were the blade depth. This is a well built unit. The only other issue is if you don't guide the first foot of wire out of the cutting area it can get stuck in the outboard fan motor housing and jam up the motor. If they had a small cover over that spot it would fix the issue and if they added a carry handle it would be nice as well. I highly recommend this if you are going to strip large lengths of wire. I have had this unit now for over 6 months with no mechanical issue.
