I bought a Gizmo, but completely stopped using after a few times. By the time I get the gizmo out, set it up, and get going I could already be done rolling a few
coils. My 2.5 mm screwdriver and kanthal are always within arms reach at my desk, so its easier grabbing them and doing it manually. I thought a coiler would help me wrap nicer looking coils....nope, they look just as good done by hand.
This one looks nice but price is steep and I'd probably end up doing the same thing anyway. I'm a lazy ........ Although you can do the same thing that coiler is doing to help you wrap nicer with a screwdriver. Instead of pressing the kanthal past the handle, hold the kanthal along the screwdriver handle similar to how this coiler works, and your fingers will be out of the way of your wrapping.
