Review: Great product with excellent instructions - I was truly amazed how well this register worked. It did an excellent job helping to heat a very cold mud room in the winter. Recently I moved it to our bedroom during a heat spell with high humidity. The circulation in our forced air furnace which our heat pump is connected to isn’t great. Our bedroom was very warm. This register help to cool off the room very quickly. It was like a different room after the register ran for a short period of time. The manual was simple and clear and the message was if you have any issues at all contact us immediately! I would buy again. Review: Great Device - No more expensive portable room air conditioners that last less than 5 years!! These work to cool living areas: kitchen in the mornings, bedroom at night. Can't say they are 'quiet' when fan is set to high (8-10), but it's not invasive, more like airplane engine noise at cruise altitude (white noise actually puts most people to sleep, the reason so many people take a flying nap). Settings are simple to make and so far, no problem with digital panel working as expected. Important Note: these plug into electrical outlet, so carefully consider whether they can plug in near your target register vents. Elec cord is reasonably long. I've only used these for one month (summer) with central ac cooling, so can't speak to longevity, but with my bdrm door closed for an hour before bedtime, they bring temperature down abt 10 degrees (with ac running, then I turn central hvac off at bedtime, bdrm stays cool all night). Colder rooms help with getting to sleep. One more thing. These vent units measure the air temp blowing from the vent, not the room temperature. You select the vent temp -- for summer mine is set to come on when vented air is below 70; next winter over 80. Note: an issue arises when trying to set both at same time (not a flaw, issue is covered in instructions), simple to set it once per season. ## Features - Quiet Register Booster Fan: A quiet fan system designed for improving wall and floor vents airflow from HVAC systems to increase home comfort. - Eliminate Uneven Room Temperatures: Biowind smart register vent equipped with programmable LED controller and high-precision temp sensor to work with HVAC.
