It's design and functionality is well thought-through, that clear even from the neat packaging. I'm so glad I didn't follow national consumer organisation test results. My girl has the Oral-B io6 and thought it was a step down from the old Oral-B and now wants this one as well. If I may nitpick, the button is too sensitive causing accidental touches, that's a bit annoying but you'll get used to it. The only thing slightly worried about is that the button is not covered. Overtime bacteria may build up in the tiny spacing between button and main unit. But Philips and Oral-B have that issue much more at the bottom, this is already much better designed.
