Review: Works Great, Easy Installation - I was a bit skeptical of this item at first, had a different product years ago that didn't seem to help. But the second story in our home tends to run 3-5 degrees warmer in the summer than the main floor where the thermostat is located and took the chance that this may help. Installation was quite easy, just make sure you get the right size, loved that they had a variety of size choices unlike many other competitors. I admit, it took me a few minutes to understand how to lock in the settings correctly, but got them eventually. The highest fan speed is a bit noisy, but we are a fan family and it's more just like background white noise. And we'll take the noise because the velocity with which it pulls the air is quite strong, you can feel it from several feet away! We are very happy with the unit, when the AC is running, it cools the room to the exact same temperature as the thermostat is set, even a degree lower sometimes! That being said, you have to understand how it works. You program the cooling temperature lower than the thermostat setting by a few degrees, but not colder than the temperature of the air when the AC is blowing. The fan should be off until the AC starts blowing, and once it senses colder air, the fan turns on. This means that when the AC is actively blowing, it makes a significant difference in the room temperature. However, if there are longer periods when the AC is not blowing, the room temperature will creep back up because the unit is off (as it should be since it would then be pulling in hotter air just sitting in the vents). Just a word of caution so you have realistic expectations. My only minor complaint is that it does seem to take a couple minutes to turn on after the AC starts blowing, and stays on for a couple minutes after the AC clicks off. But it's a minor issue and does not seem to detract from overall performance.
Review: Keeps bedrooms cooler and improves AC circulation - Exactly what we needed for the upstairs bedroom! They pull more of the AC cool air up to the room and keeps the rooms cooler. We can raise the temp in our thermostat as these little fans are keeping the rooms at our preferred temp. They are easy to install and setup as long as you follow the directions. We’ve been running one in each bedroom for about a month now and at full fan speed (10) with no issues. The power cord is long enough to reach an outlet. Highly recommend as these are a great value and work as described. The remote works fine, but I just don’t use it as it’s easy enough to adjust settings on the register.
