Customer Reviews
This review is specifically for the variable speed ACTIVE AIR ACSC Duct Fan Speed Adjuster, the one with the blue speed band on the front and the open vent on the top. I bought this to use with the Mainstays 20" High Speed Fan that i purchased from Wally World. Amazon's tendency to mix reviews of different items makes it very difficult to judge how well a product will work for a particular application.So I took a gamble with this one and ordered it. I needed some way to slow this fan down just a little bit. The fan generates blade noise even on low speed, which is normal, but irritating when the fan is used in a small room.I had to rotate the receptacle in order to allow the fan plug to hang down when plugged into the device, because the receptacle is rather high on a wall. Plugged it in, plugged the fan into it, and turned the fan on. I only had to slow the fan a little in order to reduce the noise level to an acceptable level.With the mixed up reviews for different items, and not knowing how the devices were utilized by purchasers, it's almost impossible to determine why some of them melted and/or burned up. Especially if the items were not used properly or abused. I'm using this item as it was designed to be used, and it's working properly. Your experience may differ.So far, the device is working exactly as advertised. The fan is slowed, the device is not generating any excessive heat, and it appears to be worth having purchased it. It is a variable speed control. It does NOT have three preset speeds, High, Medium, and Low. You can vary the speed from Off to High, or any speed in between.July 8, 2019Still working as advertised. The device is barely warm to the touch. So far, so good.July 27, 2019Still working as advertised. The device is still barely warm to the touch. Just a guess, but I suspect that the melting/burning issue that some folk have experienced may be due to running fans at their highest setting and using the device to slow them down. I've been using the fan at it's lowest setting and slowing it down even more. If you run the fan at its highest setting, the device has to stop a greater amount of amperage, which creates more heat, and might lead to the unit failing. Just my 2 cents.
