Buying a toothbrush shouldn't be this difficult!
I have spent over two weeks researching what Oral-b electric toothbrush to buy. We have used this brand for years and have been and have been satisfied. As the battery is deteriorating, decided to buy a new one That is when the real problems arose. My wife bought a Sonicare per an AI recommendation. She didn't like it...too much vibration and difficulty maneuvering. I then started trying to figure out what Oral-b to buy. Very, very difficult as they use numbers for some, others have names and numbers. There appears to be a huge difference between models, particularly when you when you enter the "iO"series (1 through 10). Not only is the motor system totally different, but the prices go through the roof! Not a straightforward company.
