The first one I bought lasted about 3 1/2 months, and I just got a new one because I like it so much. I use it every day, many many times a day. I think all I do is wash pump and bottle parts.

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.

They work good for me. To be honest I don't remember for how long thy are given, but my son uses his computer extensively and after 6 months, still works 4 hours mainly looking at videos on the net.

Keep 'em clean and they should last much longer. I'm at the 6 month point right now and they are still working really well.

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 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.

It really depends on how much you use them but I can say that i use them for around 2-3 hours a day and with that frequency they last about a month.

Hard to say, depends on when you buy them. I'd ask the company how long they keep for, but I don't think you'll have a problem with them sitting around going bad. They're too addictive.

I use one about every 2 weeks. If you keep them clean they last a long time

For me , they last about 4 months. I use them in a home repair business but must add that I do not use them everyday.

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.

Depends if you purchased New or Old or Refurbished or so. They do last 3-5 years depending on how well they are looked after.

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

One lasts me 1 - 2 months. Your second one she be fine when you open it. I have been using this product for a couple of years now. I have bought multiples b/4, and you shouldn't have a problem.

I'm not sure. I never had a problem with mine. I used mine up already and I don't believe they last as long if they were dated. If they were dated ten years from now, would you want to wait that long to see if they were still good?

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.
