How long do they last for ?

Still using first pair, rinse after use, soak in used baby food jar with a little fresh mouth wash and rinse in water when ready to use again. No signs of wear after 2 + months and I get much better sleep now and even use them for a nap

I'm ussing a pin for one year or more, with no problems. I bought other because I lost one pin. I wash them with water and soap every day. I cut the plastic arc and join both cones with a thin thread more longer, its a very good solution for my nose.

They are made of sturdy wash and reuse plastic. My husband has been using his for months. I expect if he doesn't lose them, they will last for years.

They are made of plastic so they will probably last quite a while. You just have to clean them up every so often.

They seem to last for a long time. I did not see any spots on them and I have had them for a couple of months. After this weekend, they are all gone.

Expiery date? If you mean how long do they last, mine last 6 days. The expiration date is the time manufacturer says they are safe to use them.

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.

don't know. When I buy them they are usually good for 6 to 12 months or longer.

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

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. :)

I have used these for about 4 years. They have been lasting close to 1.5 years. I have had no problems.

So far they have lasted about 6 months. As to buying locally, I haven't found any store that sells them.

I'm not sure entirely, but the computer will complain if they are too old (planned obsolescence). They have lasted for anywhere from 1.5 to 2.5 years has been my experience.

I had mine on a shelf for over a month and they were still fine. I would imagine they have a shelf life of at least 6 months or longer.

It depends on if you're using them continuously. I would say you can get about 8-10 hours (though this varies). You can extend the life by removing the batteries when you don't need to use them. You can also buy replacement batteries, but they tend to be expensive so I would recommend buying new ones.

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

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.

They've lasted me over a year. I use them in my esthetics business and they are really soft and do last. Haven't had to throw one away yet and I bought mine over a year ago.

They last a pretty long time...depends a lot on how much you use them and how many layers of fabric you cut at one time.

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.
