I purchased this MSD 3503 Mini Stripper Crimper to build two 8 mm spark plug wires for my motorcycle. The device was easy to use and provided great crimps on the very first try. I am very happy with the results, especially considering the price of the device.However, if I had a large number of spark plug wires to make up or had to build multiple sets, I would definitely spend the $100 plus for the professional crimpers. Otherwise, this small tool works just fine and will always have a place in my tool box!
