Query: Works great!

Does what it's supposed to do - it froths milk! It's ultra-fast, too... it takes about 6 seconds to froth enough milk for a latte using 2% milk.Highly recommended if the frother on your espresso machine doesn't work well, or if you have a stove-top espresso maker and want a latte/cappuccino every now and then!
