how long does one last?

I don't use it everyday - only a couple of times per week. You only need 1-2 drops. It took me about 6 months to use one bottle.

I use this product every third day and the bottle lasts about three months.

I use this device a lot in my cleaning business so they only last about 2 to 3 weeks. I would guess several months with normal household use.

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.

Mine has lasted at least a couple of hours. I haven't needed it longer than that.

I think it's the standard (90) day or possibly one-year. My first one failed rather quickly after the purchase so when I returned (shipped back to manufacturer) there wasn't any dispute. The replacement one is still working for the most part but still the quality isn't spectacular.

I've only had it a few months. I use 3 times a month maybe 4. Seems to be made of good quality so if I had to guess I would say would last a while.

It depends on use. In substantial use, a few days.No use, or little use: few weeks.It last far more than its competition

Not very long, I would say about a good 2 and 1/2 to 3 weeks. Wish it was longer!

It varies. Over 25 sticks, at least. I usually break the sticks in half. One half lasts me 3-4 days or so.

From my experience, it lasts for at least a year unopened. That is why I like it so much.

Depends if you purchased New or Old or Refurbished or so. They do last 3-5 years depending on how well they are looked after.

Maybe 1 1/2 days. I'm satisfied for the price. I bought 2, and one worked a month and quit. I sent it back, and they replaced it. They work fine now.

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've had mine about a year, use them every day for at least 3 or 4 hours. Still perfect.
