We bought the 500 as a replacement and travel toothbrush. Our Triumph 5000 (absolute top, but also correspondingly expensive) is in repair. Now that is the electric toothbrush such a thing: one has even befriended with it, then do not want to return to manual mode. So replacement was needed. So we now have the direct comparison: top model at an attractive model.
After a week of intense Oral-B 500 use I must say I'm impressed and satisfied. The cleaning result is very good. A simple but useful flush timer is also included. The battery lasts 4 days loose by (at 3 times brushing per day (I even know my wife 2 times)). The loading and base station is pleasantly small and thus very well suited to travel.
The workmanship is very good and high quality. The 500 is completely waterproof and therefore washable under running water after use. In controls, there is a normal on / off switch, an on / off switch for brushing with timer, and a small LED for the status of the battery. The timer used as a time signal überigens the motor of the toothbrush, which is rafiniert right. Every 30 seconds the engine jerks gently but clearly audible. Then you change the mouth to the next area.
All in all, the Oral-B, a clear price / line champion. Therefore, it has the 5 star also clearly deserves. Those looking for an affordable entry into the electric dental care will find an excellent product. Other models offer more safe feature that but even at much higher prices.
Finally, a tip: the 500 is supplied with a "Precision Clean" brush. In our opinion, the "Micro Pulse" brushes are considerably better and slightly more expensive. Give it a try.
