After buying one and using is for about a month, I bought another so I could keep one at the office and one at home. It works, but sometimes doesn't stay all day especially if you go outside. But it's better than nothing, and there are no other options on the market that I could find.. Another reviewer said there's not much product in the bottle -- well, there is, but it does seem to vanish much more quickly than other hair products. I don't use it excessively but it's already half gone. (And it usually takes me a lot longer to get to the halfway point with other products). So I agree that it is overpriced.
