The shipment went smoothly and quickly. What else one is not accustomed to Amazon.
The piercing is great. The material is well tolerated. Had no problems with the switch. The piercing can be in the length of cut well, because for me it was just a little too long. After shortening the surface was a bit rough, but went to a couple of times now and ball screw again. After that I was able to use the piercing light. After cutting and the molded thread is starting, but as I said before, simply unscrew the ball a couple of times up and down and it goes back quite easily.
