Seems like a good controller, hope it works well for you. we shall see

Only thing to note is the amperage rating, the control is only good for 3 amps draw. I don't know how much the fans draw, I would assume less than 1 amp each, but if they're more than one you'll be pushing your luck with the controller running both.

true, ill test them both most likely to see but i feel it should be under the 3 amp draw

Most, if not all fans should draw way less current than that, under an amp for that matter, unless there's a dead short somewhere in between or in the fan, in that case you surely would notice a firework show instantly or shorty after power up.. If you were to hook three or more fans to that control, than I can see it being a problem..

Except that the inrush current when starting the fan is often much, much higher.

The spike when powering up isn't gonna hurt the control, even if it went well over 3 amps, it's only for a short few seconds..

I usually advise, make sure a solid state control is rated for at least double the rated current draw of the fans.

I usually advise, make sure a solid state control is rated for at least double the rated current draw of the fans. I've had ceiling fans spike up well over 3 amps many times upon power up on my kof transformer based control, and it still works wonderfully.. But I also always power up on high... To be off subject: And the majority that do videos and power on the fan starting on low and working up to high speed, I'm still trying to figure out who started this and why? If it's a timing thing to make videos short, the time it takes to power up the fan to get a consistent rpm on low is about same, or longer it takes the fan to down draft from high to med, and med to low.. Virtually there is very little or no time difference in the sequences.. Point is, that kof transformer based control you got from eBay, it being rated at 3amps, you should have no issues using it either to do videos with ceiling fans needing the control, or using it in a permanent location with one of those CG fans.. Note, when you power up the fan using the high speed on that control, you are not using the control's transformer, as it's using full power from line.. line / Switch / fan I usually have a control on the line I use for videos.. Right now I still have a Moss Caribbean Breeze Mark V control hooked when I did the Magic Heat video, and the Hunter Studio that I'm currently doing, and have the control set to highest speed, basically just going through the control, and not using the control's transformer..

A control should only slow down a fan. A fan without a control will run on high. If you find a control that speeds up a fan, rather than slows it down, something is seriously wrong and you should NOT use that control. My videos go into detail about this. Which video is that Dan?

Often times people go up from low to medium before its even reached full low speed.

Most recent was the A52? but I talked about it in more detail in other videos.

I do agree about the flywheel... But the majority does it on every fan..
