Mio Star Wasserkocher

Very good stove, efficient and quiet.

Good value for money

A very good kettle, very good product.

I am very satisfied. works perfectly.

This is a special kind of review because I'll be suggesting a way to solve the loud noise that this kettle does as well as reviewing it.

Review
pros : works well, fast, we can choose between several temperatures which covers most use cases.
Cons : loud, loud and very loud. Everyone will hear that you're turning it on, especially if you live in a flat. You've been warned. It bothered my girlfriend so much that I resorted to crude surgery to solve the issue, see below.

Workaround
Be mindful and remember that electricity can kill you. So unplug the device and let it rest a bit before proceeding. So this thing can be opened from the bottom with the help of a classic Philips (PH) screwdriver. Keep track of the screw positions. When every screw is removed (including the one hidden behind the power cable), you will have to pry open the case to reveal the internals. I did it first with an old credit card to separate both sides (top and bottom) working my way around the case then I used several bits to finish the process. This can be done, you need to pry and pray (that you won't break anything). As most manufactured items nowadays, it's secured by clips that ties the thing together.
When you manage to open the thing find the culprit (see album here https://ibb.co/album/chvYKv) and break that noisy b*stard once and for all. I used my reliable Knipex to do so but anything will do. Don't break the circuit board by doing so. You only need to remove the cover and remove the circular metallic piece, that's where the noise come from (check here https://www.youtube.com/watch?v=cNZ-w5XYVZ8).
To reassemble reverse the process and enjoy your now almost silent kettle. I'm not skilled at crafts and I managed to sort this out so if you're bothered by the noise don't hesitate to do so. You'll feel proud and everyone will appreciate your gesture.

Migros, if you read this: please consider adjusting your noise levels for your next iteration of your kettle. I'll probably check elsewhere given what I had to do to make it bearable.

the kettle works well, heats up quickly and is not particularly noisy when heating up, contrary to some opinions. only 4 stars because the touch screen is poorly thought out - when the kettle is switched off, you can't see the buttons - after use, you have to press several times for the "long" press (4s) to be taken into account for switching off the appliance.

My goodness, if only I had read the reviews here before buying. I can only agree with the previous reviews. The incredibly loud and totally unnecessary beeping is extremely annoying. I don't even dare put water on for tea early in the morning. I'm always afraid that I'll wake my neighbors in the noisy house where I live. And yes, you can't see the water level on the scale either. But in my opinion, this is really only the lesser of two evils.

I replaced a previous kettle that had served me faithfully for 15 years, and this experience led me to buy another one from Migros. The promotion was also interesting for me because it is not the cheapest, but the first time I used it I realized that it was a bad buy, because when I fill up with water, I can't see how much I'm filling up, the display is behind the handle and not visible, with the old one it was on the side and I didn't see it, so I will return this faulty design. Wasting water and electricity is the whole point of this appliance. It's a shame, I've just seen that opened products cannot be returned. A designer like this should be slapped in the face. I am very disappointed.

I am very happy with the kettle so far, as I drink a lot of tea, I can set the temperature precisely.

It is miserably difficult to observe the water level. Only possible in good light. On two occasions, the lid has popped shut just as I turned on the tap. What I like is that you can set the desired water temperature. I'm less happy with the fact that I always have to unplug the tap when it's not in use.
