Review on Oral-B iO Series 9 Electric Toothbrush with 4 Replacement Brush Heads, Black Onyx: Dental Care Made Easy by Sarah Pullen

teeth clean ; allows me to improve my brushing technique every time I use it (I missed some areas because I'm right-handed); The app gives me good tips on how to reach these areas. The app makes my routine a little bit interesting and even desirable because I'm curious about how well I've done it and where. Cons: I wish it could automatically sync to my phone after using it in unmanaged mode - without having to launch the app; the vibrations are too strong for me, the brush is a bit noisy; While the mouth wide open is handy for accessing some areas, it does result in toothpaste splattering on the mirror, iPhone, etc. I wish the handle and head were a little smaller to alleviate this inconvenience; the charging travel case does not have its own battery - it comes with a separate charging cable, i wish the case could be charged via a standard usb instead of having to carry another charger in the travel bag.
