Review on Irrigator Waterdent Smart Flosser V300, black by Ewa Bonecka ᠌

I poured water, the irrigator worked for a minute, then turned off, all the buttons were stuck. The buttons have not been pressed for several hours. Then it worked again, but the buttons again stopped being pressed, and this time I could not turn it off, I had to wait until the auto-off worked after 2 minutes. Then I packed it in a box and returned it. :) Before him was B. Well, a similar story happened to him, but after a year and a half. I don’t understand, it’s like we live in the 21st century, why it’s still difficult for manufacturers to make an irrigator that would just work without glitches. I checked the battery, the charge was full, and then recharged it again, it did not help. So it's definitely not the problem.
