Powerful frother with a long rechargeable battery life
Color: Black
After purchasing three of the battery operated frothers. I finally found this amazing frother. It is very powerful so you do have to be careful not to slosh liquid out of your cup when you’re using it. But I have found it helps if you rotate the frother in a stirring motion while you are using it. That really helps keep the liquid from overflowing out of the cup. It has a sleek design and is rechargeable and the charge less about two weeks.I love this one so much. I take it with me when I travel. I actually left my original one at my mother’s house the last time I visited her and have ordered another one for my house. Highly recommend.

Great Power and Creamy Foam
Color: White
This frother is amazing and has really good power. It creates creamy, smooth foam in seconds and works perfectly for iced lattes, cappuccinos, and matcha. I love that it’s rechargeable and lightweight, but still feels strong and high quality.
As someone who loves coffee, this has become one of my favorite tools for making café-style drinks at home. Easy to use, easy to clean, and looks beautiful on my coffee station.

Powerful easy to operate but splashes
Color: Black
Excellent frother--Very powerful and easy to turn on/off with one button. The only downside is it requires a deep container in which to froth. The frothing pitcher I had was too small and milk splashes everywhere. There is no lower speed so it works fast. I am using a deep insulated container now for frothing. Otherwise, very quite, easy to operate no pushing down on the top like other frother wands. I love it as long as I can control it to limit the splashing.

Froths Milk in Seconds
Color: Black
Frother I had for a couple of years broke. Based on reviews I bought this. Love it being rechargable. The POWER! It froths milk in seconds. Also great for that after workout protein drink. Also is a little longer than my last frother so it works great with larger glasses.
