The Stand Is the Unexpected Favorite
Color: Gray
I use this at my morning coffee station for mixing powdered supplements into my coffee shake — more than one goes in and it handles them without complaint. For a small battery-operated device it has real power. Cleans easily. The foam quality is good for home lattes without any particular technique required. But my favorite part is, unexpectedly, the stand. It’s sturdy and well made and gives me somewhere sensible to set a dripping frother instead of it lying on the counter. A small thing that earns its counter space.

Perfect frother
Color: Glossy Black
Absolutely love my frother. I'm actually impressed. This frother definitely makes a bigger better frothed milk.
I use this frother multiple times a day and have been so pleased with the battery life. Easy and quick to charge. Love the reliability of this little gadget

This is the one!
Color: Gray
I ended up going with another brand, which I returned because it was impossible to insert the batteries into the too-tight compartment (other reviewers had the same issue and I should have listened). So I bought this one and not only is the battery compartment ample size and easy to insert the batteries into, the company even sends you two AA batteries to start you off! I also very much appreciate the fact that you don't have to hold down the button, just push it once to start and push it again to stop. It's powerful and I love that it sits in its own stand and looks nice in my kitchen while doing so.
