About how long does this usually last you?

I started using mine in May, and I still have it, a little less than a half. I do not use it twice a day however, only in the morning. Hope that helps

I only use the serum at night sparingly so I try and make it last 6-8 weeks!

at least a month. I think there just samples, which is why there is so little.

I haven't quite gotten through my bottle but I will say a little goes a long way!

It lasts quite a while. I don't use mine much but I have only put one set of batteries in.

It depends on how you use it, generally speaking, it should last for at least 2 to 3 months.

On high, about 4 hours...low-med maybe 8-10. It is hard to say exactly, I generally only have it going for an hour or 2 at a time.

It usually lasts about 4-5 months...there are only two of us in this house though, so it may not last as long with more people.

Sometimes it can take a day or two for the reaction to get going. If it takes longer then there may be something off in the mix. Once it gets going mine stays pretty regular for 2-3 weeks.

I can't say exactly how long they last, but it's decent. long enough that I don't remember changing them

I suppose the answer to that question would probably depend on how long or how often you used it.

It really depends on how much you use them but I can say that i use them for around 2-3 hours a day and with that frequency they last about a month.

Mine lasted about 8 hours. I've only needed it a couple times. I was overall satisfied.

I have with no issues at all--I usually leave it on 30-45 minutes. Not sure if it matters or not but I figure longer has to be better, right? GREAT PRODUCT ;o]

I haven't had mine very long so can't verify the information, but according to the specs it is supposed to last for 50,000 hours of use which works out to over 5 1/2 years of steady use. I don't expect something like this to last that long, but it would be a nice surprise.

They last quite awhile actually. I change mine out weekly, even though I never see more than minor wear on them.

at least a couple hours! I typically drink it though within that time period so if it went longer I wouldn't know.

Mine has. I've had it for about a year maybe, and that's what I usually do.

Mine has lasted for about a year and a half now. It all depends on what your using it for and how many times.

I've had mine for about 10 years. I use it for 20-30 minutes almost every morning, six months of the year. I guess I still haven't hit the expiry point!
