Query: Small, powerful and fast

I always put half and half in my coffee this frother does a good job of whipping it up. I experimented with lighter 1% and 2% milk it creates a large bubble of froth in seconds and actually makes the taste a little better, although I still prefer half and half in my drink. This is all from cold milk, I like the hot cold combo.It's powerful and takes no time to create a good froth. The design seems a little small though it's solid, unlike my old frother that would actually vibrate so much the battery holder fell out daily.My only negative is the on switch is hard to push up (for off) so I've ended up with a few splatters of milk over the kitchen counter/wall. No big deal as it has two on settings so I never flip the switch fully on.
