Button Broke!!

I initially loved this mixer, its quiet and mixed the formula very well....perfect!! After using it for 3 weeks, the button stopped working, so thinking it was the batteries, I replaced them. It still doesn't work. We never immersed it in water, the button just broke. Now I have to buy another one (different brand of course) or go back to the good ol fashion way of shaking it up. Anyone else have this problem?
