Chimney Balloon 30"x9" Inflatable Blocker (Large Chimney Pillow

Product deflated every 1-2 days. Hot/cold air and temp changes impact this a lot.I’ve submerged to see if there is a hole and there is not. Save you money and buy something else.

It really works. I procrastinated for months due to the price but this really works. My entire first floor is much warmer and no draft

We had considered this product for years but weren't sure if it would make a difference. I wish we hadn't waited so long. The temperature on the Great Room floor has probably risen 2 or 3 degrees because the draft stopped. I would recommend this to anyone who feels that their chimney is loses heat.

Perfect ...it works so well at keeping out the draft.

The balloons keep deflating. Need to be reflated regularly. Flimsy and thin for the money.
