Excellent product

A great product, easy to install. We use it to control the blower on our fireplace logs and it has made a huge difference.

speed controller

nice unit

Great Speed Control!!

Have a shaker motor to keep the blast medium flowing to the sump on my bead blaster cabinet. Without the control, the motor shakes too much and is annoying to the point that I turn it off soon after starting. With the speed control, can set and keep the motor RPM at a pleasant hum at start-up and continue until the blasting is done with no dry spells in medium pick-up. I tried other controls and this one works best for me!

Works like a charm

This unit does exactly like it says. I use this for my exhaust fan in my indoor veggie garden. I have had this hooked up for a couple months.
