The Philips Sonicare DiamondClean HX9911 electric toothbrush is almost identical to the Philips DiamondClean Smart HX9954/53. It is simply delivered with the charging glass and the travel case, and has “only” 4 brushing modes.
It integrates the guide of the best toothbrushes under the label “best product” of this category, all prices combined. It thus takes first place ahead of the Oral-B iO Series 10 (from €371.75).
