    Very pleased with the downdraft barometric damper and the FAST shipping! You guys are awesome! I actually had an issue with trying to place the order online. I called and the gentleman I spoke to knew exactly what the issue was and he was super friendly. If your shipping address is different than the mailing address of your credit card, make sure that is correct in the online form! My bad! LOL
