Easy to follow instructions, easy to install and product works great.

I could almost feel “suction” when I used to open my bathroom door. The bottom of the door was very close to the floor and apparently, it sealed to the door frame pretty well. It started to develop mold on the ceiling. I’m sure there was negligible return air going back to the air handler when the door was closed. Likewise, I’m sure the exhaust fan could barely function with the door closed.
I removed the door (I’m barely handy) by removing the hinge pin and cut out the bottom of the door as shown in the directions. The In-Door Return Air Pathway installed easily.
Now I can open the door with ease and even close it by just pushing it and letting it shut on its own. No way was that happening before. I’m confident the ventilation will be much better now.
Before installing, I removed the cardboard insert and spray painted it black so it would be a little less obtrusive. It came out great. Maybe Tamarack can make that change for the future.

The air whistled around and under the door until I installed this air return. It has sufficient area to return air from three or four air inlets. It is very easy to install just cut a notch in the bottom of the door and then slide it in and insert two screws!

This is the third one that I have purchased. This installation took less than 15 minutes including door removal and re-installation. Looks great and provides the return air flow required for the room. I will be purchasing additional registers for other doors, Do not second guess this product.
