Super happy with this purchase and so glad it's rechargeable. So much better than the fancy brand we had that went through batteries like crazy and had a wobbly shaft. Lots of power and can be easily used for travel as we do for blending protein powder and cream into coffee. It's already traveled to Europe twice, Tahiti, Australia and a Panama cruise and still working like the day we got it. We're very pleased with the quality and the price.

Frothing like a barista!

Color: Gloss Black

Works great! It took some practice to produce froth without the coffee splattering! But, once I got the hang of it, the results were amazing!
