I can advocate that they are crap for teeth hygiene! I had one for about a year and had so many issues. I've switched back to oral b io9

Oral B...specifically Oral B iO (have the series 9–goes to series 10). Cosmetic dentist recommended a basic model but I told him I'd been using the expensive Series 9 iO for 2 years.

Ja osobiście używaj io9 od 3 lat i jest to jeden z najlepszych zakupów w moim życiu. Czyści tak dobrze że przestałem myć zęby 2 razy dziennie i nie widzę żadnych problemów, ale pomaga też fakt że nie jem w ogóle słodyczy

I had the oral b io9, it lasted about 6 months and died - it was replaced under warranty and that one lasted about 9 months and died. So I asked for a refund and bought the Sonicare prestige and so far so good two years later, both brushes are very good.

Tannlegen min anbefalte også elektrisk tannbørste, men det burde være av den dyrere sorten. Oral-B iO 9 eller høyere. Dyr som fan, men definitivt en oppgradering fra de som koster 200 kr på tilbud

Interestingly, the (Braun) OralB iO are made in Germany, at least the io9 I got from an auction is. P&G is a garbage company, but I have no intention of purchasing the original branded heads, which is what they are actually making money on. (there even is a local company specializing on making the "aftermarket" heads) It's worth noting that all the recent scientific literature seems to be pointing towards oralb having better results, specifically the oscillating-rotating with micro vibrations.
