The dial makes it so easy to dial in the exact speed I need for different bits, and I love that it remembers the setting when I turn it back on. Feels solid enough on my bench and works perfectly with my motor.

I was initially worried about the plastic housing, but it's actually very sturdy and the dial gives you such precise control over the motor speed. It's been a solid addition to my workspace for repeatable settings.

I’ve been using this for a few weeks now and the heavy duty plastic casing actually feels more durable than the metal one I had before. The dial has a nice resistance to it, so it’s easy to land on the exact same speed every time I switch between projects.
