Hi to you all, I bought this dental jet recently as having periodontal care, I need great dental hygiene. I had a separate container device with which I was very satisfied, unfortunately the cord connecting the hydraulic jet central sank and cut. A force to shorten, my ear glued to the center ... so I erased what worries me about directing a compact: the result after a few days grip is rather satisfying. The charge takes a week, it takes up little space even with its charger, it is easy to dry after use, and forced air provides a significant comfort, all for a relatively decent budget. The downside is that it is better to use both hands to manipulate and not for the people a little sharp and rough in their gestures ... a flexible and softer tip would be welcome.
