why do they have to be replaced so often? do they wear out (become compressed and won't stay in) or because they get dirty?

i would have to go with because they get dirty. i accidentally left a book (a REALLY heavy book), for an extended period of time on a pair i had been using and they were as flat as a penny and within a few minutes they were back to normal and usable.

Mine lasted for several days before I simply replaced them. In my past experience they get compressed and do not seal.

Mine are out months and don't dry up. They usually end up getting replaced because they are covered in crickets, etc.

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

I think these are better for cleaning. The more you wash them the more they seem to degrade in quality.

They are designed to be disposable after a few uses. I have extended their life by tapping out the dust in a waste can and then rinsing thoroughly. I have even run them through the dish washer which does not seem to harm them. Otherwise, replacing them as needed can be an expensive add-on.

When ever it becomes too soft, dirty or just plain worn out is what I go by. They can last quite some time

I do not think so. It is suggested to change them once a year. It had been about 5 years before I purchased news ones. I just keep cleaning them till they where not cleanable anymore

I haven't, and the reason why is because the cost of shipping the old pair back, plus the cost of shipping the replacement to me, is too close to the price of just buying a new pair to be worth it. I use them at the gym and just accept that they are a product that will wear out and need to be replaced.

If you contact customer service, they will replace these. They had a bad batch where the zipper didn't seal properly. Customer service has been very good.

Only when they crumble or break down. Otherwise you should not replace them.

I don't use it everyday and only change for new pair when it get extremely dirty! I would say one pair would last me half year~ It can be shorter for you since you are going to use it everyday!!

I change when I start using them when the house starts to dry out, the reason to change them is because they will start getting mold/mildew on them and start to stink.

I replace mine every year just to be safe. They probably would last a lot longer but I am careful and want things to remaindry.

I'd say as long as you clean them regularly you can replace as needed. No tears or discoloration your fine. Just boil them for 5 in or so.

Try rinsing them with water and let them dry before using again. I use the middle size file most of the time, and it has not smoothed out at all. Unless you are using yours for something other than filing your nails, I don't know why they would wear out. I have noticed that, after a number of uses, the file is full of debris from my nails. Thus, you need to wash them. Hope it works for you

The earbuds that came with my phone lasted about a year before the earpieces began to come apart. It was my own fault though. I carried them in my bag without a case or any other protection. So they were constantly being crushed against other things. I would say if you have or can get the originals, take good care of them. It really is hard to replace that quality without spending too much money.

Mine lasted about 10 months. So life span is not an issue. If you run 5 days a week and put them into laundromat once a week, then you may want to buy 5 pairs at a time.
