Do not rule the 650 out because of it, you do not have to use this feature, but if you do, just be aware of the conditions of use. Inevitably the battery will run down on the Pro 650. With approximately 28 minutes of cleaning time. When power is low, the battery status icon on the front of the brush will illuminate red to notify you of this. The built-in timer in this brush is, in my opinion, a highly underrated feature. It is all too easy to think we have been brushing for longer than we have, as many of us get bored when completing a mundane task like cleaning the teeth. This built-in timer makes it simple. There is no excuse not to achieve the full 2 minutes. However, female readers do not be put off by the colour as this is a lovely slim and comfortable brush when in the hand.

If you are really keen on logging your toothbrush activities then this has some benefit. It may be more interactive for children, as it does have some nice graphics; but the whole process feels like a bit of a hassle. In my mind, if you are really keen on logging your toothbrush cleans, you are likely going to be opting for a more premium brush. When you power on the brush with a single press on the power button, you launch straight into the only cleaning option on the brush, the daily clean mode. This lasts for two minutes and at 30 second intervals, you will hear the sound from the brush change as the oscillation of the brush head changes ever so slightly to indicate to change quadrant. If battery life is an issue the brush can be left constantly charging, technology in it will stop it from taking more power than it needs.Above and below the power button are a number of raised grips which your thumb naturally catches on.

Electric toothbrushes that are clinically proven to be superior to manual toothbrushes, providing benefits in removing more plaque for cleaner teeth and healthier gums. Oral-B electric toothbrushes remove up to 100% more plaque than a regular manual brush, which is why they are recommended by UK dentists and hygienists. Oral-B electric rechargeable toothbrushes (from Pro 600 model upwards) also whiten teeth starting from day one by removing surface stains. Electric toothbrushes are suitable from ages 3+, with specific kids electric toothbrush models available, and are gentle on gums and suitable for sensitive teeth. Electric rechargeable toothbrushes come with replacement toothbrush heads, which should be replaced every three months. Turn the brush around and the smooth white plastic rear panel is home to an increasing number of raised grips which are practically placed and functional. It will last on average 7 days. That is based on 14 two minute cleans or approximately 28 minutes of brushing time.

To be honest, this is pretty much the average. For more cleaning time you will need to go bigger, heavier and more expensive and possibly too pay for features you do not want. However, to prolong the life of the battery, it is good to run the battery down regularly and at least once every 6 months, deplete it completely. The whole app is engineered for the more premium Smart Series brushes, which the 650 is not a part of.​
