I bought it last week.
It has many positives.
Among them is that it makes a cup easily without needing to dirty a whole pot like you would with a regular coffee maker.
It makes very little noise and shuts off on its own.
It is easy to understand where the water goes because there is no other place it could go, I would like it to be written in the instructions or at least have a picture (okay, that's my quirk).
I simply cut the regular filters because the compartment is small, for one cup I use 2 small measures (it has its own).
I also use it without a filter to get water at the ideal coffee temperature, so I make Nespresso-style coffees or tea, where I don't want the water to be boiling but warm in general.

Finally, if we follow the device's guide and fill it up to the point it defines as the upper limit, we don't get one cup.
This is easily solved if we measure the amount of water equal to 2 cups, from those it has (=250ml in total) and as soon as it reaches the middle, we fill it up with the rest. At least that's what I do and it serves me very well.

Overall, a very good purchase, nice taste in coffee.
