How long does one last?

It depends on how much printing you do. You'll see on the product description an estimate of the number of pages it will print. The capacity of these, I believe, does diminish as they get older and the ink dries out a bit.

There's no real way to know. Too many variables: what you are printing, how much color, what colors, printer. Are you printing in draft or picture. In my experience they last for months, but I don't print a lot and it's mostly draft color.

I don't remember the last time I replaced one, so I'd guess at least one year.

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

It varies. Over 25 sticks, at least. I usually break the sticks in half. One half lasts me 3-4 days or so.

If you're asking how long it will last, I would say for about 3-4 months maybe even longer!

If you are referring to how long I have had the unit and if it is still operating I have had the unit for over a year and a half. it is still working well. If you are asking how long the charge lasts it depends on use. With moderate use I can get two to three days on a charge.

Mine last between four and five days depending on how long you have them on.

I don't know for sure. I have kept mine from 2 to 4 months, with one going about 6 months. I can't say that I noticed any difference.

Not very long. And mine has been having issues since about a week after I got it. So I do not recommend this one.

I think it's the standard (90) day or possibly one-year. My first one failed rather quickly after the purchase so when I returned (shipped back to manufacturer) there wasn't any dispute. The replacement one is still working for the most part but still the quality isn't spectacular.

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

It lasts quite a while. I don't use mine much but I have only put one set of batteries in.

I've only had mine for about 2 months, so I can't speak for how long they last. Fortunately, no issues thus far with them.

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 just got mine and only used a few times. If used properly, I don't why why one cannot last for a very long time.

The one I purchased lasts a good 8hrs but I don't know if I just lucked out or something :)

Obviously, it depends on how often you use it, however. I don't use it every day and it lasted a long time.
