how long do they last ?

A long time, they will stay absorbed with water as long as they have water. If the water dries up they shrink back down. I have to throw them out sometimes because my kids squish them apart but besides that they can be used over and over.

Lay them out on a towel to absorb the water and let them shrink back up. I also spray them with a 50/50 water/vinegar solution to prevent mold :-)

They hold water quite a long while. I have not added any water since I put them in my container, which has been well over a month.

Hard question. I have some that I enlarged a few months ago, they can still be played with. My main concern would be if they get moldy. Some have started to fall apart but it's probably from the kids playing with them. You can just add some more water if they start to dry out.

What do you plan to use them for? Using them for hands on play only lasted us 3 or 4 days then they were breaking easily in our hands, however, we only used a very small portion of the bag so we have plenty more to make other days.

No, I have not. And so far, I have not had any problems with them lasting for weeks and even several months.

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

There is a little variation with some but, on average, I would say about three weeks. I've used them for about a year in two separate locations in the house. Hope this helps.

I have had them last 5 years with just moderate use per day and up to 3 years with heavy use recharging twice daily..I also do rejuvenate them after that time to get an extra year out of them before I buy new

I'd say they last a good 18 months or so. Recommend this product, but cover or remove in winter; it will crack with repeated hard freezes.

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

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.

They last quite awhile actually. I change mine out weekly, even though I never see more than minor wear on them.

I really don't know. I had bought it for my mother in law. From what she has told me, they last a good while.

They last about a year. I have been buying them for about five years and Amazon has the best prices. I think you will be happy with them. Hope this helped.

As long as you cleean them properly they last. I have had mine for 2 years, just brought em out last week for a project and works great. Just be sure to properly disassemble and clean them and thes are a fine investment

I suppose It depends on the amount of usage. But I have had mine since November 13. Used moderately but not heavily. A couple times a week for 30 min to 1 hour each time. I like them. If I could afford the $40 a piece ones I would get those over these any day. But for the money they do what I need them to so and so far no sign of wear.

They seem to last for a long time. I did not see any spots on them and I have had them for a couple of months. After this weekend, they are all gone.

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

I'm not sure entirely, but the computer will complain if they are too old (planned obsolescence). They have lasted for anywhere from 1.5 to 2.5 years has been my experience.

Exactly 167 years, 5 months, 28 days, 4 hours, 37 minutes.I'm kidding. I have no idea, but it would seem that with proper care they should last a few years. :)
