    Great quality of electric toothbrush, but a lot of the features that are included aren't entirely necessary. Lots of other toothbrushes out there that are cheaper, and still get the job done.

    A step backwards for me

    I first owned a sonic care tooth brush. It flung the toothpaste off and the back and forth motion was to short unless I turned up the speed. At that point it’s to harsh on ones teeth. So I then buy a $15 sensitive oral-b toothbrush. Works great. No vibration caused by way so small of motion. The head spun a full 1/4 turn back and forth. Next I bought this brand new oral-b electric toothbrush. I turn it on and was a bit disappointed when I see they went the rout of sonicare. The head twists 1/10 of a turn back and forth very quickly. Just like with my old sonicare it flings off the toothpaste. I just cannot win. The speeds of all these brands of electric toothbrush are way to fast. If the oral-b would slow it down a bit and bring back the longer spin range it would be perfect. Think about it. If you start off with excellent teeth and use a manual toothbrush regularly and efficiently you will have great teeth. How fast are those bristles moving with a manual brush?? Not very fast. What does that tell you? These electric toothbrushes are seriously to fast. Slow them down and increase the range of motion so the bristles can more effectively sweep the teeth clean. So to wrap this up. I recommend the $15 oral-b sensitive electric toothbrush. Now also why I will stay with oral-b. When I used a sonic toothbrush the sweeping motion would actually shove food into my gum line. The faster the setting you use would cause most of the toothbrush to fling off the brush. So I ended up having to put toothpaste on my finger and spread along all my teeth. No way. Never doing that again. The spin motion of oral-b kept most of the toothpaste on the brush. When brushing towards my gum line because the oral-b spun it would actually shove food away from my gun line. Oral-b decided with this toothbrush to move more toward a vibration motion and it now flings some of the toothpaste off. (Very annoying ) although definitely not as much as sonic. So please with the next oral-b tooth brush get away from Sonic motion and bring back the range and slow it down .... For now I recommend again the $15 sensitive oral-b electric toothbrush. It is a great toothbrush at a tiny fraction of the cost

    Overall this is a decent toothbrush. I am on the 3rd week using the io9 and when I brush my front teeth the noise from the brush vibrates my head slightly. I never used the app for the tracking as I feel that is useless feature
