Rated 3.0 out of 5.0 by 12345 OK but not perfect.
I had Up-Dux installed in some of the rooms when I had a new swamp cooler installed.
They get the job done very well as far as air circulation is concerned, & blowing cool air up into the attic rather than out a window should help a lot when the hot weather comes.
But.. be forewarned that the spring loading of the trap doors make them open& slam shut with the slightest movement of air. Here in the desert, we have a lot of afternoon winds & the Up-Dux can be annoying at times.
Of course this doesn't happen if the cooler is running. but, if it's off, they can get a little noisy.

Rated 2.0 out of 5.0 by FairExchangeAdvocate In theory - a good idea ...
Let's see, where do I start. Odd size, at least to my thinking. If you look at what they want to pass off as a register you almost laugh. Lightweight plastic grill. Their idea of closing it is to remove it, insert a piece of cardboard (included) and screw the register back in place. Yikes. So, I bought a good quality 12 x 12 register that will open or close but it's a little too big. Next size down, 10 x 10 is way too small. The only thing it's got going for it is the spring loaded flap that opens at very slight pressure differences but it's pretty flimsy. I'm disappointed.

I purchased 6 Up-Dux and I am very happy. No more opening windows to vent my evaporating cooler. All I have to do now is open and close doors to direct the flow and cool the rooms I want. There is a plastic cover that slides in and out of a slot in the side of the grill to shut the unit off completely in the winter. It is very quick and easy to do. Installation directions are easy to fallow and the units are quick and easy to install. All 6 in 3 hours. Pay attention to height clearances so the flapper door can open properly. I placed one a little too close to the edge of the roof and the flapper bumps into the roof when the cooler comes on. Units can be installed without going into the attic, but I did go into the attic to be sure the insulation was in the proper place to get the the most cooling efficiency. Made In USA always a PLUS.

The dux work ok, but, there are a few drawbacks.
1. I would go into the attic to make sure that your chosen install location is clear of obstructions.
2. I haven't heard of anyone else complaining about this problem, so I haven't come up with a fix for it yet. The problem is that when the wind blows, the spring loaded lid flaps up and down. It makes a heck of a racket, so forget about sleep. However, this is when the cooler is off. When the cooler is on, this won't be a problem due to positive pressure keeping the vent lid open. The company should make the spring pressure a bit stiffer, or a way to lock the lid down. This would especially be useful in the winter when you wouldn't want the vent to open at all. The insulator sheet that slips into the vent grill, does not provide much insulation, or noise barrier. I can say with some assurance, that had I known what I know now, I would not have bought the up-dux. It would have been much cheaper and a lot less work to just open the dang windows.

Rated 5.0 out of 5.0 by Texaschickengeorge Best thing I've done.
These work great. Keep all the windows and doors closed. I have 5 in my house now. House stays much cooler with the air venting to the atic. Helps reduce the heat there too.
