Me three. I have a Towa gauge and rarely use it. The problem with it is you can't just set it and it magically works. You have to do a lot of testing and practicing, then writing down what thread you're using, what your tension settings are, the batting type/brand, etc. Then once you use that particular combo again, check your test results to see what tension setting you should use.
It's MUCH easier and faster to do what Cindi does - lift off your hand.
