Also an iO9 owner here; since July; bought it specifically for the 3D sending tech, coaching and HealthKit syncing. This because after my last Oral-B ultrasonic (70 CHF model) failed I went back to manual brushing because I was too cheap to replace it; I got some gum rescission and extra tartar for my decision. The new purchase was made with a goal to protect my gums. (Since using, I saw that I was pressing much too hard, and in adjusting my technique, this sensitivity has abated; totally justified the investment as the dividend is healthy gums and back to low tartar build up.)I have an iO Series 9, the model this replaces, it is totally worth the money, completely changed my dental health and it is the closest you will ever come to a dental cleaning, great tech.
I actually don’t mind using my phone to track, I just launch Spotify and listen to music while holding my phone to track my progress.
As such, don’t really see the need to upgrade since the new “feature” is not beneficial to me. I would highly try to grab the 9 series if it gets marked down.
Fully agree with ALL this posters comments and recommendation.
Had oral-B electric brushes since the 1990’s, 4 different models covering rotary and ultrasonic heads and I think the rotary ultrasonic head of the iO series is really great.
My only concern is that my ultrasonic model had a rubber on/off button that after about 2 years allowed water inside to wreck the unit; 3x units failed exact same way. Terrible material selection unless controlled failure was the goal; which I thought it was. I looked at Philips but they didn’t have HealthKit syncing so I’m hoping the iO’s thin membranes over the switches aren’t so crap as their Ultrasonic units (I took a chance because I got a free 4-year warranty.)
Only performance issue with my iO is that the orientation is not quite sensitive enough and occasionally confuses the chewing surfaces for the sides of the teeth; this requires user to tilt the brush head a bit to make it clear to brush which surface is active.
Regardless, can recommend. (When it launched it had a msrp of ca 500 CHF. I waited a year and bought on sale for ca 250 CHF. Also, replacement brush heads are pricy but they do a much better job than the other types.)
