Excellent customer service. The products were exactly as described delivered as promised. Very pleased with this purchase
I have an office that is frequently too cold, and this product solved the problem. It's reasonably easy to install. I would definitely recommend it. My only complaint is that it's hard to move the louvers. You have to apply a fair amount of pressure, because the metal mesh above louvers is pushing against the louvers, creating a lot of friction. Maybe this won't happen to everybody. I suppose it might depend on the design of the vents in your office. Either way, I'll only subtract 1 star for that problem. It's still a good product.
