Works great with my portable band saw that I built a platform for. My portable band saw is NEVER used by hand. It's ALWAYS in a unit that I've welded together to mimic a stationary vertical band saw. I tether the switch on the saw to the "on" position and use this product as an alternate switch to turn the saw on and off so I can use my hands. (both) to guide the steel through the cut. I've tried forgoing this product but it's too dangerous with a zipper saw switch. Using a saw without a zip tie will render it useless. So this product is a must for me.
