how long does it last

They usually last anywhere from 6 to 9 months. I make sure that there is no residual mascara left on any sponge I've ever used. I wash them with antibacterial hand soap a few times a month. I have always kept them on the bathroom counter (in or on a seashell) when they are not being used. I have always cared for my sponges because they are not always easy to find. I really love these. This seller has the best quality that I have found in a long, long time. Invest in your complexion and a natural sea sponge. I think you will love it, especially if your skin is thin and sensitive.

I have used some of these sponges for over 6 months. The smaller ones tend to fall apart much sooner. I have learned that they can be cleaned using a hydrogen peroxide solution, but most don't need this.

I don't know to be honest, you use it twice a day, and you only use 1 oz. each time. I guess I would say mine has lasted me at least a month, but sometimes I forget to use it (on average forget 3 or 4 times a month).

it lasts about 3 to 4 hours , with about half a year of use it reduces to about 2.5 hours to 3 hours

I'd say ours last about 3 weeks, considering it stays on for a half hour at a time and we usually put it on 2-3 times a night it's not too bad but we will probably invest in rechargeable batteries for it. It is a lifesaver though!!!

I use it two or three times a day. I buy the giant size, so it last about two months.

That's hard to say exactly. If you use a couple of drops each time (like it recommends) it should last for months, or longer.

Mine lasts for about 2 months easy. My setting is "Clean" so it runs for 2 minutes each time I brush.

Hi. I can't realy answer that question as I have not had it long enough. I can only imagin that it would be at least 5 yrs which would also depend on how often u use it. I use mine maybe twice a week in between by big vacumming cuz we have a dog and it works great for the constant pet hair. Hope this helps.

It lasted 2 1/2 months. It's a great product, at first i didn;t think it was working until my stylist noticed my hair was growing again. I was using it because I had radiation treatment in 2012 on top of my head and it left a thinning spot on top. this product is worth the money, just use as directed and it will work.

I have had it for almost a year and have not replaced it yet....if you keep it clean it lasts a long time depending upon how much its used.

Mine lasted about 8 hours. I've only needed it a couple times. I was overall satisfied.

This doesnt last very long.....probably 3 weeks for me....depends on how much you use and how often. So it can get expensive. But it is the best.

Quite a while. I don't have a lot of hair to cut so the charge lasts a while. I've gone a month without charging it.
