Mine and my friend's lasted less than a year and then would not hold a charge. complete waste of money.

I'd say ours last about 3 weeks, considering it stays on for a half hour at a time and we usually put it on 2-3 times a night it's not too bad but we will probably invest in rechargeable batteries for it. It is a lifesaver though!!!

I've purchased 2 of these from Amazon. The first one lasted just over a year and now the one I have seems fine and it's probably been a year or close to it. The information I got said it should last 1 year to 18 months.

I think about a year. I've used mine several times (several times a day for a few days in a row), over a period of 9 months and it's still fine.

I have had mine for 7-8 months, and one before that on another trick for a year. I was very pleased with both, and would not hesitate to buy another.

It usually lasts about 4-5 months...there are only two of us in this house though, so it may not last as long with more people.

So far mine lasted over a year. Just follow the directions as it says and I feel you will be very pleased with the results. I definitely recommend it:-)

Had it for months now and I think it is supposed to last for years. First time it was changed since bought. That's probably 10 years.

Well basically it depends on the use. Im using it non stop and it lasts 1 hour maybe a little bit more.

it lasts about 3 to 4 hours , with about half a year of use it reduces to about 2.5 hours to 3 hours

It depends on how you are using it. I use it primarily in recipes so mine will last a couple of years. If you are using it straight out of the container, you need very little, so it still will last a long time.

depends on your settings. it lasts me approx 24 hours. My heat has been running more than usual in this cold weather we have been getting. I can say I am happy with it. easy to fill, does a good job. I currently use it in my bedroom.

It depends on how long you expect it to last. Mine lasted for about a month until there were so many tears at the seems that I threw it away.

It lasts for several months, depending upon the size you purchase. I have several dogs so I get the larger size for dogs (but not the largest) and it lasts me at least three months.

it depends on how much you use it. When i used it my son was up twice or more a night and it would run for 15 to 20 min each time. So it lasted a couple of weeks.

I'm not exactly sure. I've hardly used it since I bought it. It seems to last at least a couple hours. I really don't know. I'm sorry.

In my experience it lasts approximately 3 weeks, when you use it once a day.
