EZ8 Smart Register Booster Fan

Works well. We have a small bedroom with one vent; the room stays a few degrees warmer than the rest of the house in hot weather. This fan brought the temperature down three degrees, we run it continuously, not on automatic. It makes a sound similar to a normal fan running so if you like to have a fan running for background noise you will not mind this. We have had this for over a week now and running fine, cannot speak to how long this will last over time, but seems to be well made. Very Happy!

Buy it now!70 ac set to70 main level temperature65-67 basement temperature75-80 Townhouse bedroom second floorin master and other room in summerPlug in pull vent set it on top set fan to high room will be 65 - 67 nice and icyCome winter will move to basement vent to pull heat down there probably buy a 2nd for down there for winter crazy how this will change your life 3 years of dying and complaining about heat in room this fixed it . Obviously best way is have hvac in vent installed but save the money and just get this

Works like a fan, like the auto on and off but thought it would cool a bit more than it does

These were absolutely life changing. If your HVAC cannot effectively reach upstairs, buy these now.We had 20 days over 90 degrees this month, and have slept so comfortably. Last Summer it was 71 degrees on the main floor and 85 degrees upstairs. I have recommended these to my neighbors, and those who actually listened have all reported back the same life-changing stories... along with being upset they've dealt with sweltering heat all these years when there was such a simple, inexpensive and effective solution.Some reviews mention the noise, but I say "whatever." Low speed is pretty quiet and works plenty well, and you'll get used to it in a night if it even bothers you at all. I could see someone complaining about the noise at higher speeds, but we've never needed them, and frankly you'd get used to it anyway--it's basically just white noise, and some people pay stupid money for white noise machines. Some reviews also complain about the power cord... Are you kidding me? For the benefit of a cool, comfortable night's rest, I could not care less about the cord.By way of scenario... We're in a three-story townhouse community built in the 70's with zero insulation on the front and back walls and four inches of attic insulation. Everyone in the neighborhood melts upstairs in the Summer or opts to camp in their living rooms or basements. The usual advice is to spend a few grand to better insulate the attic and open up the walls to add insulation. We got one of these after a neighbor recommended, were amazed at the results, and the next day got three more for the rest of the upstairs registers. What a small price to pay for virtually unbelievable results vs. adding attic insulation and tearing open walls and ceilings to install a split HVAC system.Side note, while these worked insanely well and I could have stopped, I kept going. I added R-38 unfaced insulation to the attic along with Reflectix radiant barrier to the roof deck, which both definitely helped even more--the HVAC is operating more efficiently with slightly lower power bills than last Summer. The insulation was obvious, but it was the radiant barrier that surprised me. I very highly recommend the radiant barrier, which truly lives up to the marketing and reduces the actual temperature inside your attic. It was in the low 70's when I installed the radiant barrier, and my attic was like a sauna. It was in the high 80's when I then installed the attic insulation (poor planning I know), but here's the thing... the attic was actually cooler than when I installed the radiant barrier and the outside temperature had been in the 70's. I could not believe the effect of the radiant barrier, and recommend to everyone (depending on your latitude).

I saw several questions about this working on ceiling vents and I wondered the same. After reading the product description and some Q&A I decided to give it a try (Even thought its not technically "recommended"). I was willing to try before spending a fortune re-routing my air ducts which was pretty much my only other option. I have 8x8" ceiling vents so I knew it would not be a perfect fit. I bought this WITH the wall mount kit included (That is a must) and then bought a small white extension cord and some coaxial cable wall nail in clips to run the wire along the ceiling and down the wall. Install was super easy. It's not a perfect fit over the vent but I positioned it where the sensor is directly in line of where the air flows out (you will understand when you read the instructions). Screwed it into the ceiling and ran the wire down the wall. I set it on auto and the instructions say it takes about 24 hours for it to "learn" your system. So we set it up and waited to see. I put it just on one vent in my son's upstairs bedroom that has terrible airflow (on top of being upstairs). While he complained the first few nights about it being loud (and waking him up) I said well lets see if it works and if so you will get used to it. Let me just say it works, and it works really well. The temp in his room is now the same is it is in the hallway outside his room, sometimes even cooler. Downsides are it's a little loud (fan noise) and a little unsightly (I tried to keep it all white so it would blend with the ceiling) but they don't outweigh the benefit of a cooler room without having to spend a fortune! I would DEFINITELY recommend this, even for CEILING VENTS!!
