About Oral-B iO Series 9 Rechargeable Electric Toothbrush
Overall Feedback:
73% positive
66% were impressed with battery life, while 34% weren't
If I brush twice daily for 2-3 minutes at a time, the battery lasts for a week.
After seven months, my battery life indicator consistently shows 40% life remaining when it dies.
My biggest issue with the product is the battery life. The toothbrush won't charge to 100% and only reaches 98% even after being on the charger for a few days.
77% appreciated the brush head size, but 23% faced problems
I have a hard time reaching the back of my molars with the brush head being too big for my mouth.
75% liked the brushing modes, yet 25% didn't
I am facing issues with changing the toothbrush mode once I have started a mode already. I have to leave the toothbrush running while it's out of my mouth because I can't see the screen and then push the bottom button so that my toothpaste and saliva can be tossed all over my bathroom.
64% liked the sonic technology, whereas 36% raised concerns
My hand hurts and the Sonicare toothbrush is too loud due to its excessive vibration.
68% found the timer helpful, however 32% faced issues
I could never finish brushing in the recommended 2 minutes due to bad programming.
