They made us have it in our classrooms during the H1N1 outbreak, but beyond that I won't buy it. In my mind, okay it might kill the germs, but then the dead germs are just sitting there on your hands. I'd much rather wash with soap and water and have them rinsed away.
Of course if there is no water or soap available then I might use it but I'm kind of on board with the Anon above (aside from calling everyone names) - I'm wary of everything being antibacterial.
I avoid it if I can. The only time I'll use it is if I've been somewhere like Caps describes, and I'm planning on eating.
I've got sensitive skin apparently and if I use it I generally get weird little blisters.
I have it in my car, at my desk and in my purse and use situationally like after I get gas or use an debit machine or handle money. I aslo have anti-bacterial soap at home. Superbug shmooperbug. I don't want people's†poop cooties on my hands when†I'm eating my sandwich, ffs. Blerg.
Never. Ever heard of War of the Worlds? I have the world's strongest immune system because I have been exposing myself to as many cooties as possible since birth. I can eat things that would make a billy goat puke and wash my face with a toddler's t-shirt. At the worst, I get sick maybe once a year.
