The addition of SmartGuide, an LCD, and is actually rather gadget to all redundant ways because the brush indicates when to change brushing area, and when the pressure is too strong. And that is the only downside of this brush because this screen is pretext to show the price of all over 96.
Otherwise, nice finish, rather thin compared to other models, compact charging base, and providing a carrying case is a more certain.
To summarize, excellent brush, extremely effective, its price is artificially high in my opinion because of its SmartGuide, but it takes something for everyone as they say ...
