Speed Bully Motor Fan Speed Controller 120V, Variable Speed Controller for Electric Motor, Fans, Pumps, Routers, AC & DC Motors, Inline Duct Fan Controller, Perfect AC Motor Speed Control

This tunes my 750 cfm Vortex down to a pleasant 63 db at 250 cfm, although Speed Bully barely can start the motor at that setting.

Arrived quick, however it did not provide any variable speed function on the motor I tried to have it work on. I did all the prior research and this should have performed its job yet it didn't. Will be returned.

A must have if you want to change the speed of things. So make sure you grab 1 or even 2.

The unit worked great but only last a few weeks. Cheap junk! It gets really hot while your using it which should have been a sign to me not to use it for very long. Oh well!

Blows fuses, can not buy the fuses locally, but other than that when it works it does exactly as I need it to do

this product works fine, I dont need my fan running fun blast and this saves on power, its the second one i bought and havent had any trouble with either. works great.

Just what I wanted for my grow room fan.

It has worked very well for me
