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.

Easy to use, reliable machine

Color: White

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.
