Nice handheld frother!
Color: Glossy Black
Handheld frother....tiny but mighty! Holds a charge for a number of uses before needing to plug in. Easy to use, easy to clean and works well. Doesn't take up a bunch of real estate on the counter or in the drawer. I would totally recommend this product.

Perfect for Protein Coffee & So Easy to Use
Color: Gray
The SIMPLETaste Handheld Milk Frother works great and has become part of my morning routine. It mixes protein powder into my coffee so much better than stirring with a spoon—smooth, frothy, and no clumps. It’s lightweight, easy to use, and powerful enough to quickly blend coffee, protein powder, creamers, or even matcha in seconds. Cleanup is simple, and it stores easily in a drawer. If you love adding protein to your morning coffee, this little frother is a game changer!

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

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
