In my testing of six cubes, the average time until it burnt out was 10 minutes and 16 seconds.

They would take a really long time with a lighter. I use my stove and it takes 10-15 minutes. If you can't use the stove a small fire will sometime be a better alternative. I have not been able to use a lighter to light one it would just take too long.

They last about 2 days for our dog. We used to get the small, but they were gone in an hour or so.

I put them in late at night and have checked in the morning and they are still warm. I would say a good 12 - 14 hrs at least. Usually I have replaced them by then to make it through another night. Use them as warmers for strays in my neighborhood.

You just bend them and they light up. They last probably about 12 to 16 hours but my kids will put them in the freezer if they still have a lot of time left and when you take them out of the freezer they stay lit up for awhile longer.

These work great, however they burn fast so you will go through a tube in less than a day. I don't remember any smell and they don't give off a black smoke.

I don't keep them on longer than 30 minutes. The packaging could improve the directions!

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

Hello: They don't melt quickly. I estimate approx. 5 to 10 minutes. It also depends upon vaginal or rectal use.Hope this info. helps you.

5-6hrs. Depending on temp I guess. They do heat up when in use. Use units for a quick 10-20% charge if need.

If you cut one in half, I think 10 minutes is accurate. A whole one, approximately 15-20 minutes. They actually melt pretty fast.

They do not stay warm long. Actually they really never get "hot", you get about 15 minutes of warm as long as you are constantly kneading them. After about 30 minutes there's almost no heat at all. Activation is another 30 minutes of boiling water and waiting for them to be "completely" fluid again.

They last one year. They don't burn out but they loose potency or the ability to kill the bad guys... just get tired and weak.

I use these bulbs in a candle warmer that I use probably 3-4 times a week for about 3-8 hours. The bulbs last about 4-8 weeks in my experience depending on frequency of use.

9-1/4 burning area long and they burn about an hour if no breeze. If it's windy, they burn down fast. I light one or two depending on the bug population on my deck area but I keep them by me and they do chase the bugs away. Yes, you can snuff them out and relight them but don't leave them stuck in a pot outside cause then they absorb moisture and until they dry out fully, you cannot relight them. Did that. I also have the much larger ones I purchased at Gardener's Supply but expensive although they last 2 hours each. I also, sometimes, light one and carry it with me when walking dog so the bugs stay away during that time.Gardeners supply doesn't sell anymore, Amazon does and they are called Garden Insense Sticks and cost $16.99 for 12 that last 2 hours. These, Murphy's cost $11.99

It's not recommended to use a regular lighter to light these coals. They need about 3-5 minutes over stove size flame. Well worth the waiting as they last longer, burn better, don't smell, or taste bad.

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