How long does it last after one aplication?

It worked for two years the first time I used it. Then I started to get some weeds and wild grasses and I applied it again. That's in Albuquerque though and we've been in a drought. We get some precipitation, but not much!

In Ohio, I place it on my brick patio three times a year. Fall, Spring & middle of summer if it was a wet and rainy summer.

I used it in the beginning of the summer, and it is now winter. I didn't apply it twice. I will most likely apply it again at the start of next summer. I was not measuring it, but it controlled the overgrowth situation of the woodlands moving into areas I didn't want encroached upon.

I use it yearly for my driveway (gravel) and around my house. The effect seems to last at least that long. I skipped one yearly application and still had good results well into the 2nd year, but then it seemed to wear off.

In my experience it lasts approximately 3 weeks, when you use it once a day.

I only used it once or twice and it worked. Your question makes me wonder though!

Again, depends on daily use and amount but I would say one can lasts around 3 months or so if used daily.

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.

Obviously, it depends on how often you use it, however. I don't use it every day and it lasted a long time.

For me about four to five days. My friend said she can tell a difference after one or two days.

It last for about 3 months the way I use it. I use it every other day, once a day. A product that works!

Depending on the person, generally between 30 minutes and two hours (some traces of the effect sometimes last close to that two hour mark) I generally have it work perfectly for the first 30-45 minutes then it trails off by the one hour mark, though some of my friends have said it lasted longer for them.

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

It depends on how liberally you apply it and how large of an area you apply it to. I used it once a day on my entire stomach and it lasted for three months.

One pad is good for 4 hours. It turns from blue to white so you know it's done.

I didn't use it for its original purpose, so I don't know how long it lasts. I suppose it depends on how much and how often you use it.

Around 15 minutes. It is a good product, but I think it is little expensive for the results!

Not sure, I've never timed it but I would say about 30 minutes and you can use it again.

I cant honestly say. I believe it was one year but it has not given me any problems

I am not sure, but for me it lasted for about three months - and I used it once per week, gently.
