This frother is amazing! The battery is strong. It charges fast. It’s got easy to use buttons for speed. It’s well made and I like the water resistance feature. All three attachments are sturdy. The double wire whisk froths quickly. I’ve only used low setting. I highly recommend this brand and frother.

Sturdy and powerful!

Color: Basic Silver Frother, Size: Basic Frother

Sturdy, powerful and nice looking. Almost too powerful for small containers. I like to mix protein powder in my coffee. Even on the low setting you have to watch the speed. Would like to see more attachments.

This milk frother is super easy to use and works great for coffee, matcha, and protein shakes. It makes a smooth foam in seconds and the rechargeable battery lasts a long time. I also love that it’s waterproof and easy to clean!”
