Chimney Balloon CB30X12 Large Chimney Balloon, 30" x 12"

Easy to activate and install and did the job of eliminating chimney odors in the room. Very pleased!

DO NOT WASTE YOUR MONEY!!! I ordered this a couple of weeks ago and also ordered the extension pipe. Since then I have found it on the floor of my fireplace every morning. I have taken it outdoors and used a bicycle pump to fill it with cold air to see if this was the problem... same result. This was a very expensive "balloon" and isn't worth ten cents. It will not hold air. All said, I have over $60 into a garbage bag that won't perform to any standard. Buyer Beware!

Just took a few minutes, and even though I don't think it's airtight, it does the job of cutting the draft & noise outside.

Kind of a pain to install but so worth it! We used this to keep bats out and it works! Will continue to use in winter for energy savings.

It seems like this will be OK. The plastic is hard so it doesn't really form into the corners. It still leaves a small draft. Much better than what it was. I think it would be better if it was softer more pliable plastic it would form tighter into the corners and stop all of the draft. As it is the room is much warmer with it than without it.

great product. very easy to set up and we have taken it to the new house with us now.

Trying to get it to fill the space above the flue was impossible -- and I became a sooty mess. Avoid!!

shuts out noise and no draft coming in the house. expensive but worth it
