I Bought the BWS-50-MF wire stripping machine. I needed a wire stripper to move from site to site. Paid for the copper wire stripping machine in the first week end! Later had some trouble with motor and Bluedog automatic wire strippers fixed without question .Now my BWS-50-MF wire stripping machine is working perfectly fine and is still making me money! If you are looking for a wire stripping machine, I would highly recommend Bluedog wire strippers. Simply the best wire stripping machines money can buy.
