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!

Spiral portion of blender did not hold up
Color: Black
It was wonderful for 10 weeks. We used it almost daily and sometimes twice a day. It frothed quickly. It proved a satisfying blender until approx 10 weeks of use. The wire spiral on the end started to slowly wind off. It worked OK but wobbled and frothed weakly at that point.
For short term use, for very infrequent use, it will be fine. Looks acceptable, easy to use. Changed the batteries one time. For the price, I am not unhappy.
Have now replaced it with a more expensive one on Amazon.
Thank you Amazon for giving your shoppers the opportunity to leave our feedback. It is one of your most appreciated features.

Great little frother
Color: Black
This is a great little frother. It is powerful and really frothes up what ever you are trying to stir, sometimes too much for what I want it to do. Do not get water or liquid into the motor area or the item will stop working. Recommend this item.
