How long do they last?

If you properly prepare everything, they last quite long. I added in several teeth to a broken denture. I had to go out of the country and could not get to a dentist to get new dentures. I was gone for six weeks and everything was just fine, so I kept waiting for a problem. That was over a year ago and everything is still fine.

Depends on your need. There is not enough liquid to go with all the powder. But it works good.

Depends on how you [ab]use them. If you often run them all the way down, and/or run them down only 1 or 2% and back up to 100%, they may last less than a year (or only take half a charge after a while). If you seldom run them below 30%, and don't recharge until they're 90% or less, they may last 5 years or more.

I believe they are supposed to last for one year. I have been using mine for over 6 months now and it has barely changed in size.

Can vary greatly. Mine lasted less than a year. But also had some that lasted two years.

I have been using them for 2 years. if you use them twice a day they will last 30 days. You than need to replace them. I don believe it is permanent, you will have to continue on a maintenance program I sometimes forget, but most of time I use them at least once a day I hope this helps by iluvmath65@yahoo.com

They seem to last a long time, I bought the 4-pack two months ago and I'm still using the first one. I really don't use them a lot, tho, only when I open up my pc case.

They last quite a while. I mainly use them for my son's wireless remote for his Xbox 360, he plays everyday, somedays he plays allday and on average we usually have to recharge them every 3-4 months. I found them to be better than an OEM battery we've had.

I've had some over 6 months and they are still good. They have kind of a wax outer shell so I think they would keep for some time.

They usually can last a year.....but I personally notice a difference after 6 months.

I don't know how often you use them but I have had some for up to 6 months and haven't any trouble with them. Hope this has been helpful. Thanks Bert

During the warmer months, they've lasted 2 to 3 months. Winter time, I would check every 2 weeks depending how cold it gets.

They are LED so they should lasts for around 50,000 hours on. I have had them for 3 years. I have 12 lighs throughout my home. I have had 1 go bad in that time. The whole thing (light and speaker) went bad.

I can't answer for sure, but I bought mine in March 2013 and they are still as good today, 4 months later. So, at least that long. :)
