As some have written here - when it works, it's great. Unfortunately for me, after a year and a half, the complaint for leakage (leakage through the bottom of the device). I got a new piece and again after a year and a half the same fault. After disassembly found a crack in the high pressure part of the device - unrepairable.
High pressure
Gets food debris out of the interdental spaces
Unfortunately poor quality workmanship

The name of a well-known company is not necessarily a guarantee of quality. Those days are gone.
when it works so good but it's obviously poorly designed because it's made of the wrong material which according to other reviews shows the same fault.
Unfortunately, it is only now after 11 months since I bought it that I have read the reviews here and elsewhere. It's a low-quality Auschwitz. The internal pressurised water line is made of such a weak material that it cannot last, and it has not lasted for many, many people across Europe. The consequence is that it destroyed the sink cabinet, which swelled up with water leaking from the unit. If it was just a planted tube but this is the weak material it's made of inside. It just can't withstand that kind of pressure. The machine thinks it has started cleaning by starting on the applicator handle but at the same time the elbow in the pusher itself is cracked and therefore it drops the pump. It flows everywhere inside the device to the electronics and to the charger, which has - I don't know why - a connector on the bottom. I ordered a better rated product on AliExpress for a third of the price.

We were satisfied with the device, unfortunately we had to return all 5 units we had. After about a year, water started leaking from the bottom of the units, they had no pressure and would not shut off.

Cleans the interdental space well
