Manual de utilizare e cam degeaba. E greu sa intelegi de ce apar diversele erori.
Ce nu e explicat deloc in tot pomelniucl asta tradus pe site e modul de functionare: la filtrul cu osmoza inversa, apa cu impuritati si minerale care nu trece de membrana se intoarce in rezervorul din spate. Astfel, apa devine mai concentrata si aparatul da o ER03. Atunci trebuie sa scoti rezervorul din spate, sa il golesti si sa il clatesti. Si asta trebuie facut la 2-3 zile. Ar fi fost excelent sa aiba o evacuare separata pt apa concentrata care nu trece de membrana.
In rest, merge bine de o luna, filtreaza, incalzeste, face in mare ce trebuie.
Debitul e mai mic decat la modele sub chiuveta, dar merge.

The user manual is a bit useless. It's hard to understand why the various errors appear. What is not explained at all in all this nonsense translated on the site is how it works: in the reverse osmosis filter, water with impurities and minerals that does not pass through the membrane returns to the rear tank. Thus, the water becomes more concentrated and the device gives an ER03. Then you have to remove the rear tank, empty it and rinse it. And this has to be done every 2-3 days. It would have been excellent to have a separate outlet for the concentrated water that does not pass through the membrane. Otherwise, it has been working well for a month, filters, heats, does pretty much what it needs to. The flow rate is lower than in under-sink models, but it works.

Aparatul a venit foarte repede, momentan el pare ok, urmeaza sa vad cum se prezinta in timp. Din pacate manualul de instructiuni lasa grav de dorit. Pe langa faptul ca desi l-am comandat din Romania, instructiuni in Romana nu exista, sunt mentionate butoane inexistente pe aparat, iar instructiunile sunt foarte vagi.

The device arrived very quickly, at the moment it seems ok, I will see how it performs over time. Unfortunately, the instruction manual leaves a lot to be desired. In addition to the fact that although I ordered it from Romania, there are no instructions in Romanian, non-existent buttons are mentioned on the device, and the instructions are very vague.

I’m very disappointed with the heating element on this Klarstein unit. Even when set to the maximum $95^\circ\text{C}$ setting, the water only reaches about $50\text{--}60^\circ\text{C}$. This is nowhere near hot enough for a decent cup of coffee or tea. While I haven't tested the filtration yet with the kit, the price point is far too high for a device that only filters water and fails to heat it properly. If I hadn't already disposed of the packaging, I would be returning this immediately.

super l'eau est bien filtrée ,répond tout à fait à ma demande ,silencieux et simple d'utilisation , je recommande.

Great, the water is well filtered, it perfectly meets my needs, it's quiet and easy to use, I recommend it.
