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 IO series 5-7 is what I usually recommend to my patients. I use the oral b IO series 9 (received that free from a rep). But I try to understand cost with giving my patients a high quality recommendation. But love it!!! Has a 2 minute timer, oscillates which I think is more beneficial, pressure sensor, bunch of different settings, quieter than most.

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.
