I recently got the Oral B 8000 Genius .. .and I must really say what a great toothbrush it is ... It has so many options and also great for those with sensitive teeth, since apart from having a specific option, it also alerts you if you're pressing too hard. The toothbrush connects to your smartphone through Bluetooth and keeps track of your brushing habits, and through the Position Detection feature it lets you know which areas have been covered, and if there are other parts that you've missed .. Luckily it has a very good battery life and comes in a really convenient carrying case ... so i'll be sure to carry it around in all my trips
