how long does it last

I don't believe this product does anything. We purchased a couple and a wet rag works just as well.

You need to re activate it after about 45 mins to an hour. It does work great

Not long enough. It does not work as well as advertised. I use it like a scarf draped around my neck (wet). It helps this way but does not cool like they claim.

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

Seems like it lasts about 45 minutes. Not much better than the one I replaced.

I only use it once a week. I haven't purchased a new one yet. I would guess approximate 6 to 8 weeks.

I didn't use it for its original purpose, so I don't know how long it lasts. I suppose it depends on how much and how often you use it.

It last for about 3 months the way I use it. I use it every other day, once a day. A product that works!

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.

So far ive only used it for 5 - 10 min at a time. I use it everyday for the last 2 weeks but i use it several of times a day. I just now today recharged it. So id have to say it lasted a long time. Hope that helps some.

I believe it was 1 year but I have had it longer than that and so far could not be happier. For the price it is hard to beat.

Mine lasted 6 weeks but I only used it once a day. I saw results in 4-5 weeks.

There's two of us and we use it daily. The flow will start to diminish, go this way for a while, and then stop totally. When you see it diminish, order another as this will go on for several weeks or less. We've had ours for 3 years now and it has typically lasted 12 months. Hope this helps.

It actually lasts a long time, at least two months. I use it in the morning and the nighttime cream at night, so it is hard to say. I love this product, tried many different ones before staying with this one.

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

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!!!

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.

Depends how long you're going out for. Mine lasts about an hour and a half.
