I purchased a toothbrush two months ago and while I can't say that it has cleaned my teeth thoroughly as well as prevented tartar around my gums. I only SJgave it three stars because the brush heads are too big for my mouth, causing me to gag as well as the battery life. If the toothbrush is not in an upright position, it never goes to sleep if it's laying down or if you continuously open up your drawer, it will still be on.

I see many people are complaining about how the head holds water and toothpaste, and it drips down the handle leaving a gross mess. If they would read the instructions, it clearly states to remove the head after brushing and rinse it inside and allow it to store air dry before re-assembling. If you do that, there's no mess. Works excellent!

Great cleaning electric toothbrushes. As the other comments state the rose and black special edition is definitely io9 series and not the io7 I was led to believe. The screens are colored and has 7 different cleaning modes. Very good deal when on sale for these 2 brushes vs retail price of just 1 io9!

This design is impossible to keep clean , harbors water for mold/grime . Ridiculous issue for a toothbrush . Both the heads and the handle where it attaches to the head are a disgusting nightmare . Must use water flosser to clean , then sanitize and dry disassembled and I still can't trust it .

Did not think anything could beat the sonic care tooth brush but the oral B has the edge.

My first electric tooth brush and works great

Works great and is easy to use.

I have used an electric toothbrush for years, this one is on the next level. I feel like I get a professional cleaning eveytime I brush.

I’ve had an electric brush for several years but this one is quite an upgrade. My teeth used to feel clean with the old brush but this one makes them feel even cleaner. The smily face lets me know i have brushed long enough which is nice as well.

Love oral-b...cant beat it...really cleans your teeth better than manually brushing..have had my older one for about 16 years...decided to upgrade..very happy with this one..
