how long do they last

Depends on the use. I've had mine about a year. Have a couple dings and have straightened the tips on some of them. But still use them and still works great.

depends on much u throw them and what kind of target your using. these are all factors, but for the price and quantity its a good deal. i used mine over seas and we threw everyday for bout hr a day. we had multiple diff sets and used these as extras. i still have 5 of them after a year small knives, but very sharp and durable overall

I haven't had mine long (a few weeks) but from what I can tell they should last you a while. Mine have a few dings and a slightly bent tip from hitting a brick wall, from what I can tell they are pretty durable. I typically throw for an hour or so a day and mine are all still in great condition.

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.

About 4 months. They kept really well. All in all I was very happy. Hope this helps!

It's more like they get worn down after extended use. I'd say with daily use it lasts 4-6 months depending on your operation.

It depends on how heavy the usage is on your system. They usually last about 3 to 4 months with our system.

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

I truthfully do not know. I do know that I do not change mine every 6 months. I would think that they last a long time as I have not seen any date on them.

I can't answer for sure, but I bought mine in March 2013 and they are still as good today, 4 months later. So, at least that long. :)

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.

They typically last 6 months. It depends on how much you use it. I change mine every 9 months.

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 last ok.. Like 4-5 hours.. I mean they were literally $1 each-) so the quality matches the price-)

I've kept them on both my dogs for 12 hours and they still work well. I always plug them in at night so I'm not sure how long they last. I know that even when they are immersed in water, my dogs swim, they still hold the charge.

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

I've only had mine for about 2 months, so I can't speak for how long they last. Fortunately, no issues thus far with them.
