The are very useful and beats the spray that we had to use in the past. They work for about 24-48 hours and then you need to replace it with a new one.

I've worn them several days in a row, and they seem to still last. If you're worried about serious diseases from mosquitos, I would still use some Deet, but these are fine for most outings in the US. Another tip, I've also worn them on my ankles to keep bugs away from my legs.

Some have lasted me a full 2 days. but some not even a day. So its a flip of a coin..

Worth the buy! I purchased these and worked really well for my kids. They lasted roughly about 1 Week after open and placed in Ziploc bag when not in use.

Yes, they should definitely last that long. I would guess the 12-16 hr estimate seems accurate if not longer. My kids go to bed by 8:30 and have left them on overnight and they are still flashing in the morning.

I've only had mine for a month or so. However, I'm certain it depends on how often you use them and how well you take care of them after and between each use. I expect mine will last longer than 6 mo. as I don't wear them constantly.

it has lasted a good 16 hours on one charge but i think if you charge them fully they may last a little longer. hope this helps. another thing the price is right?

I cannot answer that fully. I have not left them on long enough for them to lose charge. I have the manual at home. So I would guestimate 15 hrs? Maybe more, maybe less. Best bet is the manual, what it says, but if you don'g actively correct them for a long period I would think it would hold charge a little longer

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. :)

I would say a few weeks, depending where you put them. If you have them in a rather air-tight container, they last a very long time...if there is air exchange, they obviously won't last as long. I like them a lot but I did have one go bad on me...when I was re-charging...for some odd reason, the balls turned black...rendering that one useless...the others that were in the same condition and were heated for the same time did just fine...

I have never read anywhere how long they last. I am sure if you take care of them they will last a long time.

Haven't let them go fully dead. I normally recharge every 15-16 hours. They always last from one charge to the next. No problems with life.

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

Hum? Hard to tell. One pair lasted a week another 3 days. Depends on how long they are activated. I usually get 4-5 days but I often don't use my aides except for the evening TV.

They will last all night and probably 2 to 3 nights. They are powered by three 1.5 volt lithium batteries and can get pricey. However, they are nice and soothing. They contiuously change colors

I've had them a month and have used them for hours at a time and they are still working. I didn't think they were gonna last this long to be honest. They take watch batteries in case you were wondering.

Regular batteries (AA I think) and they last a pretty long time. I've had my first set about two years now and maybe have replaced batteries once, maybe twice. Wear them an average of 9 -12 hours a week.

I keep mine on for 30 minutes a day anyways. i just figure the longer they're on the better. 5 minutes seems a bit to quick to me.

These last as long as the higher priced ones. Being an obsessive record keeper, I can tell you exactly how long they last. I get 7 to 10 days from them, in the summer, and 5 to 7 days in the winter. No clue why there is a difference with the season, unless it is due to heat being on. (I have 2 Siemens hearing aids.)

I use these every night, on 500 lumen, for about 7 minutes. They last about 2 weeks on average. Same with other brands. The other settings will work a while longer but I need the bright light.
