Fan Speed Adjuster - Push Button Switch, Rotary Actuator, PO Operation, Black

Nice little fan controller, works great with active air fans. I do wish the plug was on the bottom back of the unit, as it would prevent the unit from sticking out. But all in all, it’s not a big deal. Still would recommend!

Quality

Will come apart of not plugged in vertical and upright. This shouldn't be a problem but it's plastic. Does the job I guess

Worked great!

I am having trouble contacting customer support, but I will update this review if I can get help.I purchased this item to match the same company's fan. And the fan is of LOWER wattage than this controller is (supposed to) output. But when you plug the fan in directly, it outputs SIGNIFICANTLY more CFM's than the top output of this controller. I would say easily 30% more. This is a major reduction. Otherwise the controller does nicely change the speed of the fan, and it doesn't heat up or anything... so... I'm giving it 2 stars because it sort of works? If the company says this is a problem I will write back. On the other hand, if this is how it is designed, then it should have been made clear in the description.

Have to start wide open and decrease the speed sometimes it runs on low sometimes only goes as low as half way not sure how good for your fan this is ,sometimes on low it just stops. And makes motor hum. OK at best
