I'm a mechanic and I've only heard good things about Noga's magnetic feet. In fact, I was so confident in them that I ordered two. They live up to the hype: it's an AWESOME tool. Having just one knob to adjust the entire arm is a pleasure. The fine adjustment of the tip also works very well. (Just a minor note: adjusting the position of the hand right out of the box is a bit fiddly. Take a few minutes to disassemble, oil, assemble, and twist the hand a few times and it feels like shit at.) If you're undecided about which dial base to buy, give it a try. I think you will find them to be a great addition to your store.
