Stainless steel. Holds a large quantity of milk (enough for two). Works well with alternative milks. Easy to clean. Easy set up and instructions. Frothing, heating, cold foam, and hot chocolate options. Perfect temp. Not 5 stars because of the constant high pitched squeel sound it makes. Almost enough to make me return it!

Hot cocoa every morning!

Color: White

I absolutely love this machine. I make my hot cocoa every morning with it. It is so easy you just put the milk in and high-quality hot chocolate mix. Push the button and then it just whips it up and gives it a little bit of a froth on the top when it’s finished. It’s so fast and easy. It would be a great gift for anybody that likes hot chocolate.

Best way for hot chocolate

Color: Black

works great, I use it for hot chocolate. Easy to clean. Something to consider though the Max light may be a little lower than shown depending on the milk you use.

Check your milk preference when buying this unit. Product Does not last

Color: White

I purchased this frother in mid Oct and less than 90 days later, it's no longer working. The wisk does not spin, and the element does not heat the milk. I am currently working with customer support on a refund / replacement, but so far not happy. I've been told it does not work with 2% organic milk and that I need to switch to whole milk, which will solve my issues. Not sure how whole milk will help with the heating element? This was not disclosed when I purchased the unit. If I had known my milk choice would impact the frother, I would have chosen another brand or product. I like the unit, it's compact, easy to clean, but it did not last.
