The product is almost perfect. I had a OralB that lasted less than 2 years! Nothing to do: the jet is powerful but still soft to the touch gums. It is of the highest efficiency. The slightly high price is a very good investment with the rest of the market. Get used to the size of the cannula that I find little. But with regard to the rendering of the product, it's a minor fault. Aesthetics is not more design. But without hesitation I recommend this product. After four months of use, I confirm my comment adding that almost daily use prevents gum inflammation. (Which was not the case with my previous product). I was contacted by the company to know my opinion on the product, with personalized advice for use, maintenance and cleaning. PERFECT. A society that is concerned with the monitoring of its products after the sale and individually, is almost unprecedented. The whole product reflects the quality of use and durability. I recommend this product without hesitation. This is not my last gadget. It stores easily and fits well in the bathroom. The more and the ultimate: it is a 100% French.
