The best frother I ever had
Color: White
I have been using frothers to make a daily matcha latte since 2016 and, since each of them lasted only between 4 to 12 months, I had purchased many of them.
This one is absolutely the best one! I bought it in July 2025 and I surely hope this will last more than one year. I will update my review if it stops working too soon.
But , for now, it has been great! I totally love the strong, fast engine. It perfectly whips up my matcha latte in just 3-4 seconds! As I use a very tall cup, I never experienced any overflowing of the liquid.
It feels heavy and stronger than my previous one, and I like that.
The reason I took off one star is because it doesn’t come with a metal stand considering that it is not possible to keep it standing up on the kitchen counter because, on the top, it has a robber cover that it is not flat. I am using an old stand from one of the previous frothers but, as this frother is much heavier, it keeps falling down. It would be nice to have a stand that fits this frother!
Other than that, so far, it is the best frother I have ever had!

Really powerful, responsive customer support
Color: Blue
Awesome for mixing protein powder into milk, Gatorade powder into water, making salad dressings, basically the kinds of work that would be overkill for an immersion blender. The unit I got started to vibrate like crazy after a few weeks. Contacted support and they said it was likely that the whisk rod was bent and said they'd refund me the cost of a new rod. We'll see if that solves the problem, but overall, I am impressed by their product and aftersales support.
