Works well. Doesn’t get hot.

This speed control works well, and stays cool to the touch even when slowing the fan down to a crawl.

I used this to control an inline 6" fan speed bringing air in from my DIY solar heater to my greenhouse and it works great. Hook up was a snap. It does the job!

It's perfect!

Control that I need

Controls my old fans speed as I need it.

it can control a fan that already has speed controls.

This product is great. Plugged it into a flat window fan that already had an adjustable speed. but lowest speed was to high for my application. It works like a charm.
