I bought this for my assistant for Christmas, and luckily my husband bought one for me too. This makes delicious, perfect temperature hot chocolate in a couple of minutes and cleans up very nicely in under a minute. Looks like Williams Sonoma is saying it is no longer available at this time on their site (and that it's exclusive). You can't froth in a sauce pan (or can you?), so after your hot chocolate has been blended and warmed, you just throw in the little frothing attachment that spins in a circle to create a rich and creamy froth on top of your chocolate. You control the amount of froth you want by just flipping it to off when you see you have enough.
