Easy to install and completely sealed the fireplace. Has dropped the temperature of the room by several degrees making the product a good buy.

Unless your fireplace is a perfect shape inside the chimney, this lets in a lot of air. It doesn't work at all.

Great idea, but didn't work the way we wanted. Returned unopened due to description not clear on Amazon, but clear on packaging.

Cannot install in my fireplace clearly not compatible with all fireplaces. Would not recommend.

Maybe it's my fireplace, but this is not practical and more importantly, it doesn't stop the air. A cold breeze can still be felt afte it is in the fireplace.Oh well

Pretty easy to install, and comfort-wise, I already notice a difference while working in the basement. I'll have to see the difference in the heating bill in the following months.

So far so good. Just installed, so I don't have experience with longevity yet. The product does what it says. Came neatly packaged with clear instructions. Hard to mess up. The balloon seems strong enough to withstand jamming against the rough brick and some pokes from a few protruding metal parts from the fireplace. The fit is good enough to lodge firmly up against the damper. We have an old fireplace that we don't use often, so I am not worried about frequently removing and re-installing. Internal parts of the fireplace are rusted and don't fit well, really drafty. I used a razor blade to carefully cut one of the pre-made slots in the center of the balloon to fit around the damper handle. With the pole, the stopper is obviously visible, but this is for saving energy, not making your fireplace pretty. Adjusting the inflation is easy, and done by blowing into a tube with a simple twist valve to open and close. You will adjust the inflation several times and move parts of the balloon around to get the best fit possible. This is an easy process, you just blow it up initially, with the pole in place underneath, until it is lodged into the top of the fireplace by the damper, then it is easy to work with. It's likely it won't be a perfect fit, but blocks significant draft. Once you think you've got it about as good as it's going to get, you can then feel around the edges for any leaks and stuff those with crumpled up newspaper, which is really simple, effective and can be done neatly, so the newspaper is not visible from the room. With a few minutes work, this has blocked the single worst source of heat/cool loss in my home. After this, I noticed cold air was still coming in from the ash box on the back floor of the fireplace, so I took a folded up rag and covered that. Barely any cold air coming in now.

I read Amazon reviews and a favorable New York Times article in late 2012 on the energy-saving value of this insulation product so I bought it. The good news is I found it made of thick gauge vinyl and it installed easily with fairly good fit around the upper inside of my fireplace. I would have rated it 5 stars but the product is costly for a big piece of vinyl and a plastic wand that probably was made in China for under $5. It's also unclear how much heat it will prevent escaping from my fireplace, but bottom line the Times said it was worth it with a reasonable payback so I bought it.

I would absolutely not recommend anybody buying this product. I have installed the product as directed and the freezing air from outside is still pouring down the chimney flue and into my living room through the fireplace doors, even with the damper closed. Very expensive for what it is, not to mention it does not work. There is no way this product can seal the chimney flue completely as there will always be spaces for cold air to bypass the product and flow into your room,especially if there is any type of breeze outside forcing the air down the chimney flue. I would say the only way to really stop cold air coming down the chimney is to install a rubber lined damper on top of the chimney flue. Somebody is making a lot of money from this product that promises a lot but delivers very little!

I recently got and installed this in our chimney. It worked pretty well, but didn't perfectly seal around the flu handle and the edges. I ended up stuffing grocery bags in any spot that wasn't perfectly sealed and that seemed to do the trick.Also note that in my case I thought the main culprit for heat loss was air escaping up through my chimney, but it turned out that it was a poorly sealed fresh air intake in the floor of my fireplace that was pouring the cold air into my basement. So stuffing that with some insulation and using aluminum duct tape made a bigger difference then this did. And that cost me a total of

This does work very well, perhaps only in the right chimneys, perhaps only when installed correctly. I have had this for four months and will adjust my review, later, if a problem develops (such as a puncture).It stops so much cold air that I need to put my hand directly under it just to feel a difference in ambient temperature. This also means that it stops the fireplace odors that were entering the room. I've even tried it with the flue open and it still keeps the cold out.It does not self-install: you have to take the time and be careful. I can now do it in about three minutes. Some words on installation:- After you THINK you have installed it correctly, feel around all of the edges for leaks. When you feel a leak, simply push - or pull - that section of the balloon into the right spot to fully stop the leak.- The balloon does give the impression of deflating, but this is a misnomer. In cold temperatures a balloon will shrink, not deflate, due to the air cooling in the balloon. This happened once, so far, to the point where cold air began infiltrating. All you need do is to inflate it a little, while the balloon is still in place (the long inflation tube makes it easy) and then check around the edges again as above.Our room has been truly comfortable for the first winter in 15 years due to this. My only concern is it's ruggedness. If it does not puncture, it will pay for itself in about 2 years. I have been somewhat intentionally rough with it to test this and, so far, am impressed that it hasn't punctured.UPDATE January 2010:Have now been putting this in and out weekly for the second winter. Performs as well as new. Seems to be quite resistant to puncturing (and it's been pushed to the limit). If it were to puncture at this point, I would buy another one.UPDATE January 2015: Still going strong! Seven winters.
