After 2.5 years, the handpiece was broken. It happened exactly one that which many have written in their reviews. Just because I had an expensive charger and many spare brushes, I bought only the handpiece again. The cleaning performance we were to peace. I hope that Philips has improved the product. If after 2.5 years, the new handpiece is defective, I will not buy this brand. Also it can be assumed that this intention is to sell devices with low life. The manure of today is tomorrow's business !!! Thankfully, there are reviews !!! Whether Philips these reviews also reads ???
