Better buy the Oral-b 7850 DLX!
I used some previous Oral-b electric toothbrushes in the past, and I was always very satisfied with them. The new toothbrush seamed to be a perfect choice, especially for the new features I didn't have before:<br /><br />1. 3D Excel Brushing Action with 40,000 pulsations and 8,800 oscillations:<br /><br />My expectation: Much more power and a different 3D brushing should improve cleaning.<br /><br />My conclusion: Didn't note any difference comparing to the previous ones.<br /><br />2.  Speed Control:<br /><br />My expectation:  Good to clean the tongue and gingival at lower speed.<br /><br />My conclusion: The control is too bad. You have to press a unique button for a long time to reach the lower velocity, and if you stop the power, for example, to move the brush from one side to another (up to down), and want to resume it again at the lower velocity, you must press the button again until you reach the lower velocity. It sucks. After an initial period I ended using always the standard velocity. Oral-b, you should put another switch where you can select the proper velocity in which the power will work: low, medium or high.<br /><br />3. Pressure Sensor:<br /><br />My expectation: Great! I always put too much force to clean my teeth.<br /><br />My conclusion: Didn't note any difference, even when I tested it, didn't note that pulsations stop when you brush too hard.<br /><br />4. A 2-minute-total and 30-second-for-each-side Timer:<br /><br />My expectation: Good to control if you clean more time or less time than appropriate.<br /><br />My conclusion:  not much useful. Many times you should stop the power, and in this case, the timer (it is not a sound, but a vibration instead) goes to zero. Other times you should keep cleaning one side for more than 30 seconds, but when you move to the other side, you lose the control of how much time you should stay in the new side.<br /><br />5. FlexiSoft brushhead:<br /><br />My expectation: To be the same as previous ones.<br /><br />My conclusion: They are the same as previous ones. Very goods.<br /><br />6. PowerPolisher brushhead:<br /><br />Sorry. I cannot use it, until I finish my orthodontic treatment.<br /><br />7. DualAction brushhead:<br /><br />My expectation: To clean better.<br /><br />My conclusion:  Not useful. The FlexiSoft are better ones.<br /><br />8. Tongue Freshener:<br /><br />My expectation: To clean my tongue better. Maybe it has some mint or freshener liquid or something.<br /><br />My conclusion: No better, not worst, than a regular tongue cleaner.  No mint, no freshener liquid, no nothing.<br /><br />9. Interdental Cleaner:<br /><br />My expectation: a good rapid substitute for flossing.<br /><br />My conclusion: KIDDING! Useless. No substitute for flossing AT ALL! A waste of money!<br /><br />As a final conclusion, the power tooth bush continuous to be good, but the extra accessories and functions are not much useful. As written in the title, I recommend you buy the Oral-b 7850 DLX instead. It is cheaper, and you would not need the extra brushheads (you can buy the PowerPolisher brushhead separately).
