Got the Oral-B TriZone 6500 ordered because I had bleeding gums after brushing daily. I was then the dentist recommended an electric toothbrush to buy. However, the Council was to choose an essay, which does not rotate. Therefore, I have chosen the TriZone because the essay only vibrates and does not rotate. Have since any more problems with the gums. The toothbrush vibrates for 30 seconds, then the next quadrant of the jaw is up. You can adjust the cleaning time and to 3 minutes total time, it vibrates just after 45 seconds. After these 2 or 3 minutes you can vibrate in rapid succession 3 times to signal the end of the brushing time. In addition, you can still select a program for sensitive teeth / gums, a program that aims to make the teeth whiter and one for tongue cleaning. The clock can track the spruced time (time is running automatically when you turn on the toothbrush), you can see what program is set and the Smiley changed his expression, depending on the well-dressed time (nice for kids). In practical terms is that the toothbrush vibrate briefly and the red light on the back lights up briefly when you press down too hard while brushing. The Bluetooth feature is a funny gimmick that toothbrush connects quickly with the app and you can read while brushing news or tips for healthy teeth. There are statistics for grooming behavior, memories, you can unlock various awards or make storing the dentist cleaning recommendations. As I said nice gimmick, but I would not miss this if I had not ... The travel case contained in the accessory I find very convenient. The holder for up to 4 attachments is also useful if multiple people just use the toothbrush or is kept to also included essay for interdental cleaning in the bathroom. The battery lasts about 10 days if to brush morning and evening.
