We use in our two bathrooms once the Oral B 'Professional Care 1000 "and eimal easy Oral B" Vitality ". With two toothbrushes to reach a noticeably better result, than is possible with a conventional toothbrush while brushing. Especially the back teeth and inner pages are thanks to the rotating brush just as thoroughly cleaned with "orbiting" movements, like the front, which is quite difficult or almost impossible with manual brushing. A significant advantage over the much cheaper "Vitality" I can with the expensive "Professional Care 1000" but do not recognize: Although the latter cleans with 8,800 rotations and 40,000 pulsations per minute, while the "Vitality" cleans only 7,600 rotations and no Pulsationsfunktion offers; in practice, however, feels the teeth with two toothbrushes to almost the same. When a result of tooth cleaning is no difference at all to recognize: in both cases, the teeth feel significantly smoother and cleaner than after the manual brushing with a normal toothbrush. The "Profesesional Care 1000" has an additional visual Pressure sensor. That sounds good, but you have to push very hard on the brush before, hence the warning light comes on. So vigorously normally suppressed anyway nobody brushing teeth to the brush, so I think this feature unnecessary. In addition, the "Professional Care 1000" a dual timer, which is a short and after 2 minutes is a longer signal after 30 seconds. (The signal consists of a short or longer break in the rotational motion. The "Vitality" has only a longer signal after 2 minutes). How though should thoroughly clean the entire teeth in just 30 seconds a jaw quadrants, or after 2 minutes, me remains a mystery. I always need almost twice as long, so me of the permanent timer pulse rather bothers while brushing. In this regard, the simple "Vitality" is to me so even better, because it logs only once after 2 minutes and not continuously every 30 seconds. Finally, has the "Professional Care 1000" still has a charging indicator light, which indicates the charge status of the battery. This function makes sense, however, is of course then be superfluous if the charging station (as in our case) is anyway always plugged in and keeps the battery trickle charge. Conclusion: no doubt it is in the "Professional Care 1000" a very good electric toothbrush, which I can wholeheartedly recommend. However, if only the simple Oral B entry model "Vitality" buys, waived my opinion on (almost) nothing, save for but when you buy more than half of the money, so that the entry level clearly is the price-performance winner compared. The round brush - and that's really to be welcomed - are identical and fit for sämtiche models of Oral B series, whether entry-level model or luxury version.
