does what its supposed to
Works great if you use little milk but the froth doesn't last too long. The actual stream frother is a million times better, both in consistency and taste, but this product works great when you are in a hurry and want to make froth quick. I've seen a lot of people say it doesn't work. First time I tried it it didn't work for me either but I was using too much milk. 1/4 inch of milk on the bottom of the glass its all you need. Insert the frother in the milk vertically and almost touch bottom of glass. Start it and move gently up and down. Keep in mind it will not work with hot milk. A little warm works, but cold works best. I used mostly organic whole milk but it works with others as well. Also if batteries feel loose take battery cover off and bend the contacts on the cover out. Good product overall.
