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.

Best kitchen device!!
Color: Black, Color: Black
This frother is absolutely amazing such power behind it . Quality is just as amazing made very rugged. And I love the stand and the best thing about it is no more batteries to change now we just charge it up. I HIGHLY RECOMMEND this product to everyone and I will be buying more of these for gifts and more for our winter home also. You won’t be disappointed at all.

Works as described
Color: Black
Love this whisk. I have arthritis and this is light weight enough for me to use. I love the push button, and the stand for it. It’s really easy to clean, and it blends my shakes nicely without leaving the powder behind.
