In the end I like it very much given the price, because I think spending more than 60 for a milk frother is too much.
I have always used long-life milk and soy milk. So I don't know how it is with fresh milk.
You need to know a few things beforehand. I didn't read that in previous reviews.
My first copy was immediately exchanged very leniently by Coolblue, but with the second there was the same problem: something kept burning on one side of the cup. You can taste caked and browned, even if only a little.
I found something on that.
If you let the milk come to room temperature first, nothing burns. So pour in already and let it sit for fifteen minutes, then switch it on.
The foam result is fine. Good firm and tasty foam that you have to scoop out with a wooden or plastic spatula.
Cleaning is not so convenient because the cup cannot be put in soapy water. By cleaning it with warm water and a brush under the running hot tap, keeping it at an angle and not letting the water flow hard, after all, the electrical part underneath must not get wet, it works quite well. So get some practice. Or you can use a cloth/rag, as recommended in the manual.
All in all: satisfied.
