Are they throw always after one use?

Yes they are but if you only use a pair for a couple hours you can seal them up in an airtight zip lock bag and it basically shut them down. When you open them back up their not quite as warm but still comfortable.

Unfortunately, yes. That's the only thing about this product that I don't like. Otherwise it's a great product, it lasts for 8-10 hours

Yes, you throw them away after one use. That being said, they last for ~12 hours.

Once the airtight packaging is opened the handwarmers start a reaction with oxygen in the air and the handwarmer ingredients, that creates heat, and lasts about 10 hours. After this time the reaction stops and can not be recharged. If oxygen is cut off, such as putting them into a ziplock bag, the reaction stops and they cool. Exposed to air again they resume generating heat, but never beyond a total of 10 hours they would have lasted if they were used continuously.

Yes, they are single use items.I use these when playing golf on cold mornings. I open one ~1 hr before playing and discard them when finished playing; therefore I get ~5-6 hrs. use out of each one. They are still warm/hot when I dispose of them. I live in Arizona where I only need them on cold mornings. I'm not sure how long they would last if I was doing outdoor activities all day in a cold climate.I used to but these at a golf store that charge ~$2 per 2 pack so buying in bulk is a good savings!

Yes, they are a single use. I use one hand warmer a day to keep my hands warm in my office to help with joint aching from typing. Very economical this way about .40 cents a day.

Yes. But each pack lasts for ~10 hrs for me. 100% worth the purchase. I wear them every day on my walk/train commute.

I use mine for pulling out poison ivy. When I am done I throw them in the washer. I have washed them (cold water, air dried) probably 10 times and they are still great.

They can only be used once. You fill them, tie the end and freeze. You tear each cube open to use them. i love them because the ice cubes do not pick up any odors!

It is one time use. Once you engage the spray, you can't stop it until can runs out.

I toss mine after 5-7 uses, depending on how dirty and/or large the loads were. I've read that some people toss them when they get squishy and/grayish, but I rarely see mine get to that point, even after 8-10 washes.Mine rarely create suds, there may be a few bubbles that pop quickly but I've never had the same suds as the chemical/commercial brands. That being said, I feel like the nuts always have my clothes clean and fresh. It is an adjustment to seeing no "evidence" of cleaning agents but they really do work!

Those are for 'one time use' according to company, but I wash them with hot soapy water (no sterilizing) dry completely , check the holes and re-use until they stop working / broken.

I never checked. I don't expect them to rip or break within a year, they seem to be made well. I use the product about 2 to 3 times a week.

I actually used mine one time. Was after the time frame to return, and it did not work correctly. I actually threw it out as it seemed dangerous.

I don't think it is practical to reuse them. We just picked them up one at a time and put them in the trash. They weren't too heavy. We ordered one each of about five different brands and did our own test to see which one worked best. This one was not the top performer, in our opinion.

Yes, one time use only. Don't waste your money. Invest in the bigger kit that is reusable!

No. They be used once again. But can use any of cloth. I even have use blue paper towels are real good

I throw them away after each use, however, if they are not torn, they can be washed out and reused.

No. you can use them over and over again. They are quite substantial. Very well made.

I frequently only throw singles. If you only load one side it will only throw one target. I have never had a problem with this thrower breaking targets. For the money it is as good as I have ever had.

It throws the same pattern everytime.. You need to buy the accessory that allows a random throw if you want that option..

I actually have this answered in my review. These bolts are a one time use.

You can reuse them a few times, but they are really not made to stand up to numerous washings and use. I would not put them in the dishwasher!
