Having been less than impressed with the various home frothers I've used, I tried the Bodum with a healthy dose of skepticism. I have to say, however, that it works better than expected. I gave it a whirl using low fat milk cold, then cold half and half, and finally, a blend of low fat and half and half. The froth that it produced in each case in which the milk was cold was initially foamy, but the foam subsided too quickly. Before deciding to return to using the spigot on our espresso maker, I warmed up the milk/half and half blend in the microwave, then resumed frothing. Voila! Just as I'd wanted. Two caveats: This review is not saying that the Bodum froth is the equal of coffee house. Maybe someone will invent a little machine for the home that can perform as well as the restaurant version. But this frother is easier to use than the steam version, and the foam has enough body to hold up in the coffee. The second concern has to do with the batteries, which are in the dome on top, and while cleaning the whisk, it's easy to forget not to submerge the whole unit in water. But this little gadget worked well using rechargeable batteries, a feature that's important to us.
