I use this every day to mix my morning protein drink. Love that it's rechargeable. And it doesn't take long to recharge. Be advised that it has 3 speeds, so when you think you're turning it off, it's actually going faster and can splatter your drink. I've learned to mix on 2, then quickly push button to 3 and then off. The speeds aren't that much different, imo, so could have one speed "on', and then 'off'.

Do not buy

Color: Silver

The worst frother i've ever used. You can't even turn it off without having to go through all the different modes, meaning you will get absolutely splashed and have to clean all the little droplets of whatever you were frothing. The power is weak. The battery did last a long time, I'll give them that. 3 months ON THE DAY the frother stopped working. A very loud noise and decreased power made it unusable. I sent them an email with NO response.

Mixes drinks well and holds a charge

Color: Silver

I bought this frother to replace a weaker frother I had been using for months. I make iced lattes with instant espresso powder, water, and milk, and this frother does a great job at mixing the powder into the water/milk. It also leaves a nice 1" or so of milk froth on the top. I love that it can be charged with a USB-C cable and doesn't require batteries like many frothers do. It's very powerful for the size.
