The Between Room Ventilator (BRV) is a low-cost solution to common air pressure problems.

I expected a much higher quality of workmanship since the item, considering materials, is very expensive. It's a simple design made of plastic and a couple pieces of thin foam. It was a little difficult to install. You have to cut the wall holes almost exactly right since the mounting holes don't leave any room for error. One of the reasons I bought this was for the claim in the description that the "acoustical foam partitions...completely block light". It doesn't and as a matter of fact it leaks light due to the foam not being glued down properly. I didn't notice this defect until after I had installed it. The light shines straight through the areas where the glue was missed. This is very annoying when I'm sitting in the dimmer of the two rooms. I purchased this on Amazon from Condar who is also the manufacturer. I emailed them through Amazon's "Contact Seller" link with no response after 7 days. I have no doubt that Amazon would take this back but after cutting holes in my walls I'm pretty much stuck with it since the seller is nonresponsive. Look elsewhere since this product should cost $10 max and probably be of better quality.

AS advertised, although a bit pricey for a all plastic product, also beware the seller will add a $5.00 charge labeled Amazon Fee.
