1. The taper isn't smooth, meaning that (in may case, with a fireplace fan) there really isn't a "medium" speed. In other words, as you turn the control towards "low" the speed of the fan stays pretty much the same until you reach a certain point at which the speed drops to the previously mentioned lowest setting. Same deal in reverse, i.e., as you turn the dial toward "high," the fan runs slow until it jumps to full speed.
2. If you set the control low enough to be, well...low, then any additional draw put on the same circuit stalls the motor. In my case I turned on a light, so we aren't talking major draw. I tried changing the adjustment (putting more load on the circuit and then setting the "low" adjustment a bit higher), but I couldn't find a happy medium. If I set the adjustment high enough to not be bothered by a minor additional stress on the circuit, the "low" setting was almost the same as the "high" setting.
So, with these limitations, this speed control is effectively an on/off switch, something I could have purchased locally for less than a buck.

I bought this to slow down a ceiling fan and it worked perfectly. I wanted to run a 50 cfm ceiling fan in my basement all of the time to keep pet smells from entering the rest of the house but did not want 50 cfm of conditioned air being exhausted constantly. I also wanted the fan to make less noise. This switch worked perfectly, I did not even have to adjust the set screw. The fan speed seemed to vary with the switch position perfectly. I read a few unfavorable reviews and I can only speculate, but it might be that they did not purchase the correct amp rating for their motor. In my case, I bought the 2.5 amp model for my motor rated at 1.6 amps.Best Deals on KB Electronics Solid State Variable Speed AC Electric Motor Control
I have Hunter air cleaners to control dust from my parrots, and the motor speeds were much too fast even on low setting, and blew more dust than they collected. I purchased these units to slow down the motor speed, and was able to mount them inside the cases for a clean mount, with the wall plate and dial on the outside. These work perfectly for my application to lower the fan speed of my air cleaners, resulting in less noise and a lower CFM rate, while still filtering the air satisfactorily.Honest reviews on KB Electronics Solid State Variable Speed AC Electric Motor Control
This is a great speed control, much better than the sunmile or whatever I bought before. I really like the small adjustment screw on it that allows me to bring the fan down to barely spinning. That is a great option that I've never seen before. My fan runs great and I can adjust it from high speed down to almost not spinning accurately which is something I haven't been able to do with some of my other fan controls.Find helpful customer reviews and review ratings for KB Electronics Solid State Variable Speed AC Electric Motor Control
The A/C unit in my condo blew air far too strongly, even on the lowest of the 3 fan speeds. It blew freezing air over people anytime the A/C was running and was quite uncomfortable. So I wired this in series with the low fan speed setting, and now I have perfect control over the fan and can get it as low as I want, and the A/C is much more comfortable. It is also much quieter. Problem solved!My fan motor is a 2.0 amp, 1/8 HP, single phase 120 VAC. This control, good for up to 2.5 amps, works perfectly with my motor. Be sure to check your motor's rating and order the speed control with the correct amperage for it.
