Works great!
Color: Storage Cover Black, Size: Rechargeable
I bought this because the frother I had was very weak. Even with new batteries, it just never had much oomph. I liked the idea of it being rechargeable and no more batteries!
I expected to have to charge it when it came, but it had full power. I have used it every day since it arrived, and it hasn't slowed down a bit. It is easy to use, just pushing down with my thumb on the top. I also love that it has a lid/case. When I bring it on a trip it is fully protected from damage.
I highly recommend this frother. It is the best one I have had - and I have had quite a few.

Great Little Gadget
Color: C-Black, Size: Model C Rechargeable
What a fun and easy to use gadget! I use it to foam Zero Sugar Coffeemate creamer for my iced coffee and it works perfectly. I thought the on/off button was on the top but it's on the side. I was concerned that I would unintentionally bump it but I don't. Easy to use, easy to clean and price is reasonable.

Good speed
Color: C-Black, Size: Model C Rechargeable
Love the rechargeable feature, works great as a frother, however, I have to get use to the on/off feature instead of the press to froth like the older unit.

Hold on tight! Has the strength to spin right out of your hands. 😀
Color: C-Stand Black, Size: Model C Rechargeable
What a pleasant surprise to experience this double whisk Electric Milk Frother!! The sheer power is incredible. Makes the most delicious blended Green Tea Match Latte, Dalgona Coffee and Mochas! The only "con" happened yesterday when I was frothing my Green Tea and the device just suddenly stopped! At the time, I wished that there was some sort of colored bulbs or other way of determining charge levels. A remarkably strong Milk Frother!
