Great product! I have a fully automated DeLonghi cappuccino/latte coffee machine. After 5 years of use, the machine's milk frothing function started to fail. I purchased this product to supplement/replace the milk frother on my DeLonghi automated coffee machine; it works great and produces copious milk froth with much less mess.

Best frother ever!

Color: White

This is the best frother ever! Works better than my expensive espresso machine frother. So easy and makes a large amount enough for 2 large cappuccinos.

False advertising--it won't froth almond milk.

Color: White

Bought this because I am vegetarian and I've consumed Almond milk for the past 15 years. The profile on this product said it would froth all milks, including almond. It does not--it heats the almond milk but does not froth it. It did froth 2% cow's milk I served a visitor, but I won't use cow's milk. I missed the return date by 1 day, or it would have been returned this product for a full refund. If you want to froth plant/ nut milk, don't waste your $$$.

substitute for an ineffective espresso machine steam wand

Color: White

On sale, this item was reasonably priced. It very effectively heats and froths milk in two or so minutes. Less milk enables a more intense froth. It easily cleans up with soap and hot water. It appears to be well- engineered. It proves to be an able companion to an espresso machine.

Would buy again

Color: White

Makes great thick foam. Will overflow if you fill to the max line— not so fun to clean up. Best results are 1/2 to 3/4 of max line. Tried heavy cream, whole milk, and evaporated milk. All three work great.
