The gentleman that started they didn't work either didn't season his humidor correctly or used tap or bottled water. Only use distilled water. I even made my own drilling holes in the cap of cigar tubes. I also made another using a small airtight container I had lying around. You can buy a whole bag of crystals cheap online.

I refill with distilled water about every 1-2 months but am not convinced they make much of a difference I woud buy the beads

About a year according to the package, I've only had mine a few mos., but it works perfectly in my little humidor (50 stick capacity). Keeps it at a constant 72 percent. You can't go wrong from what I can tell.

Depends on where you live. I live in So Cal and when the weather heats up I check every month. The Santa Ana winds will dry out your sticks fast. I have charged them up about every 2 months. Remember to season your humidor first ! I think that's why some are having problems keeping their humidity levels .

The 2 I got didn't even work! They haven't brought humidity to more than 30%. I wouldn't waste your money.

they do not last as long as i would like them to last. I am using them a lot quicker then ever before.

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.

most last about 10hrs...however there are some that I've bought that were still hot the next morning..(activate at 8am and still warm next day same time)I only need them to last an 8 hr shift at work...I have arthritis in my hands & wrists and these help with the pain of keying on a computer all day...I use them in fingerless "gloves" as far as shelf life I buy a large box & use them 5 days a week..so I dont keep them for months...they do not activate until opened ...

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

I believe they are supposed to last for one year. I have been using mine for over 6 months now and it has barely changed in size.

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.

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.

They seem to last a long time, I bought the 4-pack two months ago and I'm still using the first one. I really don't use them a lot, tho, only when I open up my pc case.

They are made of plastic so they will probably last quite a while. You just have to clean them up every so often.

They last about a year. I have been buying them for about five years and Amazon has the best prices. I think you will be happy with them. Hope this helped.

No certain amount of time. I have used these last one several months....I just use them until I think they need changing or they have started trying to come off the belt. Just a use your on judgement...

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

I have had them last 5 years with just moderate use per day and up to 3 years with heavy use recharging twice daily..I also do rejuvenate them after that time to get an extra year out of them before I buy new

They last a long time. I can't tell you how long I had the first one but I know it was at least five or more years.

They are hit or miss. Some last just as long as Duracells, but for the most part, they do last long at all.
