Stainless steel material looks sturdy and easy to clean
Style: No Stand, Color: Black
It has a compact and elegant design, in addition to feeling comfortable in the hand. In a few seconds it achieves a creamy and soft foam, perfect for coffee, cappuccinos, matcha or hot chocolate.

Fantastic foam!
Color: Black, Color: Black
Bought this so I can cut down on my trips to Starbucks and recreate those drinks "to go" at home.
It works for making any kind of foam...most recently been whipping up 1/8c half n half with it and added syrups for my iced coffees I take to work.
Soooooo worth the money. Starbucks quality foam (if you're not a coffee snob) at home. I now enjoy having iced coffees with salted caramel or chocolate creme cold foam that costs less than $2 to make at home versus $15 at the drive-thru.
Time & money saved!

High speed
Color: Sliver
Nice high speed, froths a lovely froth. I like that I won’t be changing batteries every month.

Favorite kitchen gadget!
Color: Black
I bought this for mixing powdered mixes into water, and boy do I love it. I honestly use it way more than anticipated and it works so well. I use it for everything from whisking formula to the intended purpose of frothing milk. Blends quickly and clean is easy, just put a couple of drops soap into water and turn on them rinse! Best money I've spent recently on something for the kitchen, don't even hesitate, just buy it!
