The toothbrush is what I can tell so far, in order. Previously, the PRO 3000 and was also satisfied with the cleaning results. But the battery life took in the PRO 3000 relatively quickly and you could the battery pack, as with this product, do not swap. Although in the electrical equipment regulation is clearly defined that must stipulate in battery / battery-powered equipment, the battery easy to get even Procter & Gamble does not stop it. With lame excuses is argued by Procter & Gamble, but in reality to be driven up by this planned obsolescence sales. Too bad that Procter & Gamble is necessary has its customers for fools.
