Not being a coffee fanatic, I never thought I would own such a single use gadget. My kitchen tools are multi-functioning as I have very little space to store things that won't be used. I was given this as a gift by my mother who finds all gadgety things cool. It sat in a drawer for over a year, until a house guest asked if I could make her a latte. I usually froth milk in a saucepan over low heat with a whisk, but the whisk was being used for whipping cream. I grabbed this with little hope, and to my surprise it made beautifully frothed lowfat milk in about 30 seconds. Since then I've used it for coffee lattes, chai lattes, cappuccinos, and even a tiny batch of whipped cream. It eats batteries, which is why it get a 4, but they are easy to replace. For a little gadget that is pretty much a singularly tasked piece of equipment, it does it pretty well, certainly well enough to have earned a coveted space in my drawer.
