To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
updated May 2020 Over use, the toothbrush charge started to deteriorate. Within 3 months, the charge was visibly shortened, and within May itself, the toothbrush had to be charged everyday, then finally it could not hold the charge for a single use. It isn't clear that there is a warranty exchange for this, so I would no longer recommend that it failed after just a few months. I would have expected of at least a year!
Initial review Very decent model with the essential brush without the fancier modes or functions. One charge lasts over one week and holds well. I charged it, used once and went away for 1.5 weeks and when I came back, it lasted for a week. Arrived promptly.
