The Keurig frother heats and whisks about 1/4 of a cup of milk (skim is recommended, but soy works perfectly too) in a teflon-lined chamber. You get about a cup of warm foam and a small amount of milk at the bottom. If you hold back the foam with a non-scratch spoon, pour the milk into a half-cup of coffee or tea, then spoon the foam on top, you get a perfect latte. There are max and min markings in the steamer, so you always start with the right amount of milk. There is a second max marking if you want more warm milk with less foam. The foamer base has an electrical cord, but the foamer is cordless. Clean-up is quick and easy. Take off the lid and angle it under a stream of warm water to clean both lid and whisk while keeping the eleictical parts dry. Do the same with the steamer. Wipe both dry. If you are making several lattes, you need to rinse the steamer (but not the whisk) each time, or the milk starts to form a skin at the bottom of the frothing compartment. I have had the steamer for just over a month. I love it and use it daily. For variety, I have even enjoyed foamed milk on breakfast cereal!
