I love lattes but hate to spend over $3 for one at a coffee shop. I already had an espresso machine without an attached frother so I decided to see if I could find a portable, non electric one on Amazon! Thank you Amazon for leading me to the Aerolatte. I purchased the original one first that I used at home, at work, and at our camper. I then bought the black To Go one to use at home and take to our camper on the weekends. I leave the original at work. My daughter-in-law and sister loved the lattes I made for them so I bought both of them one for Christmas. They love them! Plus, I try to eat healthy most of the time and having a warm latte made with decaf espresso, fat-free milk, sugar-free carmel flavoring for only 90 calories is such a treat and very filling! Need I say more?
