I had one of these (slightly smaller in size) & it lasted 3 years. I used alcohol in it to sanitize hands. Finally the batteries wire out & When I replace them it wouldn't come back on. I was so excited to get another one, especially because it was in black, the color I wanted. It dispensed a tiny drop of alcohol; not enough to clean your hands. The next day it didn't work at all and never worked again. I tried rearranging the batteries changing the amount of alcohol I had in it, nothing worked.  the company immediately replaced it with another one that was identically useless. So now I have two completely useless dispensers. I guess they found a cheaper way to make them ha ha
