How long do they last on average.

They last a long time, I have some from a year ago. Of course one or two of them may not last, but over all they are good.

I bought them to have a class set for my students. 8th grade middle school and they are pretty hard on them. Some two or three of the 30 I bought only lasted 3 weeks. One of the tips was pushed in and a couple just didn't move the screen when contact was made.

They typically last 6 months. It depends on how much you use it. I change mine every 9 months.

Mine lasted about five years, but they went bad because I accidentally stepped on the wire and pulled really hard, if you take good care of them they should last at least ten years imo.

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.

Don't know, I haven't had to replace them. But it's my understanding they last or thousands of hours.

I don't remember but they were standard ones and seem to last quite a while.

Mine have lasted for over 2 years and still work. After they get older than that they do not last as long and get hard in the package. I always have some left year to year because I cannot always find them when I need them.

They're good for about three years. They only last about a week so that's plenty of time.

They can last for years. I uploaded a video of mine after a few years of use, and I use them often: http://www.amazon.com/review/R236EXQTVCUJA4

If you use them properly they last about 30 days. I'm not sure how many you have around your house, but they last about 30 days once they are opened. And the "use by date" is out far enough for you to be able to use them in time.

I had mine for 2 years. They come back year after year. A friend of mine has had them for years.

Mine are fairly new (a few months old), and they're still perfect. With decent care, I figure they'd probably last a year or more with daily use. But I don't really know--this is my first set.

They last quite awhile actually. I change mine out weekly, even though I never see more than minor wear on them.

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

I have had mine for a while now, and they are still going strong. At least 5+ months.
