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.

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!

It froths, but is not dependent

Color: C-Black, Size: Model C Rechargeable

While this frother does “froth”, it has many more cons than pros. The ONLY pro is it froths. The cons—only good for a traditional coffee cup. It is not water proof, and the instructions say to keep the “unit “ dry. As you froth, the liquid naturally raises height. If you are trying to use a Togo coffee mug, or thermos type travel mug—it only works well if done it three or four levels to ensure keeping the motor above the liquid. The “rechargeable “ function DOES recharge, however- it may last 1use or a few. It’s VERY inconsistent. And does not seem to be related to how long you allow it to charge. Overall—not a good buy. I had mine maybe 3 months before it quit working. And at 2 months it started becoming spastic. Even after just being charged-it wouldn’t even froth 1cup. AVOID!!
