I have to decide consciously for the simplest version and am super happy with it. The charging time is short and the battery lasts much longer than a week until the brush has on the charging station - which is handy especially in multi-day trips, because I do not always have to carry the charger.
Brushing with sound instead of a rotating brush is unusual at first, but I have a feeling that the cleaning result is actually better than my previous "normal" electric toothbrush.
Many Sonicare models offer a variety of "cleaning programs" or a lot of other technical Gimmiks such as a "charge glass" or "UV cleaning station", although sound very exciting, but they are probably really needed or used by almost anyone in the end.
All these gadgets have but one thing in common - they make the product expensive. For the price of the top model of the Sonicare range I get 4 pieces of this model, because I can get over it even easier when the battery actually after 2 years gives up the ghost, as criticized by some reviewers.
The einizige what I would have liked is a storage box on the go, but you can buy for a few euros extra.
Who is looking for a good sonic toothbrush without unnecessary bells and whistles, is well supplied with this toothbrush.
