how long do they last?

They advertised as it can last up to 2 years, but since I only got them back in June 2013, I cant really answer that. But for now, they are all grown up, and still very active! Though be warned, there will be a few deaths here and there due to how sea monkeys are, but hey, they will mate eventually and more babies will come!

The ones I purchased didn't last nearly as long as they were advertised to but I gave them as a gift to my little 4 and 7 years old cousins so there is no telling how they factored into the little sea monkey's demise. However, I feel like since sea monkeys are moreso for kids that they should be "kid prooof" to a certain exctent but then again, maybe they had nothing to do with them dying off quickly.

They can last up to two years, if taken proper care of, and if you're super clean with handling them. If there's any foreign bacteria that the little critters don't know how to handle, they could easily die shortly after that, unless you take extreme measures to clean the whole thing.

Keep 'em clean and they should last much longer. I'm at the 6 month point right now and they are still working really well.

I only purchased them about 6 months ago so I cannot tell how long they will last. I highly recommend them because they work great and is very well made.

They last pretty long. Make sure you use quality batteries, like Duracell or Energizer. Don't forget to turn them off when not in use. I don't want to attempt to guesstimate how many hours, but we really don't have to change them often. If they start making funny noises, time to change batteries.

They last quite a long time. I have had mine for over a year now. But it also depends upon how frequently and for how long of a duration you use it for. I only use mine on rainy / grey days and for 2-3 hours at a time.

They last a pretty long time...depends a lot on how much you use them and how many layers of fabric you cut at one time.

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.

they last pretty long for me. It really depends on the type of item your using these batteries for. But for me they always last at least 5 hours. Theyre pretty reliable for me. They also take like a day to fully recharge for me, i go to sleep & when i wake up their fully charged.

Not sure exactly, but I rarely replace them, I would say over six months at the very least

They can last for years. I uploaded a video of mine after a few years of use, and I use them often: http://www.amazon.com/review/R236EXQTVCUJA4

Mine lasted about five years, but they went bad because I accidentally stepped on the wire and pulled really hard, if you take good care of them they should last at least ten years imo.

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

They last quite a while. I mainly use them for my son's wireless remote for his Xbox 360, he plays everyday, somedays he plays allday and on average we usually have to recharge them every 3-4 months. I found them to be better than an OEM battery we've had.

Mine have lasted for over 2 years and still work. After they get older than that they do not last as long and get hard in the package. I always have some left year to year because I cannot always find them when I need them.

HI, i am not sure how long they would last, but i had them installed for about a year now and no problems at all.

During the warmer months, they've lasted 2 to 3 months. Winter time, I would check every 2 weeks depending how cold it gets.

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