Perfect pushing room to room. David Weekly homes are well built fantastic homes, however a 4500 Square foot home should not have a 2ft x 18in X 7ft pantry. I built a very nice add on pantry but no ventilation. I purchased this fan and did a cut out install from another large room with decorative cover on that room. NOW I have more than ample air being pulled into the new pantry. Easy install and LOVE the outcome.

I was a bit nervous after reading reviews but went ahead and got it. I need it to be ice cold in my bedroom to be able to sleep. This baby does the trick. I'm considering buying one for my office as well since the sun beats on it all day while I'm working. No crazy sounds, fits perfectly, very easy to set up, air flow is off the charts. Honestly worth it if you need an extra boost from your vents.

It’s helpful for boosting the airflow in our third floor vents. It’s not making an enormous difference but you can feel it if you are standing close by. At the price point it sells at I think you could get similar if not more effective results by using a large fan and setting it near your vent.

Updated 12/24/2024: After posting the review below (pointing out that one of two units failed after 5 months), the seller contacted me, told me the unit was under warranty, and provided a replacement at no cost. No issues with the replacement so far. Will update if that changes. Updated rating to four stars. ## Original Review ## I have two of these, in two different rooms. Both rooms are far from the HVAC, and tend to get cold in the winter, hot in the summer. One of these units has been working well for 9+ months. It helped the room stay cooler in the summer, and warmer in the winter. I bought a second one (for a different room) about 5 months ago. It worked well for a while. As of today, it no longer powers on. The display doesn't come on when the buttons are pressed, and the fans never turn on. This is disappointing, as it did help with temperature control.

Very effective but overall a horrible product. It worked so well for about 3 months and then just stopped working. Fan stopped and couldn’t adjust the temp. Tried several times to unplug and reset, just stopped working. Sadly, we are outside of the return window. So disappointing
