Unlike the slightly more premium Pro 2 2000 the Pro 650 does not have a pressure sensor built into this and this is another area that keeps the cost down. A pressure sensor illuminates when too much force is applied to the teeth through the brush. If you feel you would like such a feature then you must take a step up to the Pro 2 2000. 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. Having used a wide variety of electric toothbrushes I do believe the power and clean offered from the Pro 650 is as good as any of the more premium brushes, it just does not offer the range of cleaning options for those serious about oral hygiene. On the very bottom of the brush is a recess into which the charging stations prong will sit into to transfer power without a physical connection to the brush and in turn keeps the brush stable on the stand. 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.

However, female readers do not be put off by the colour as this is a lovely slim and comfortable brush when in the hand. Above and below the power button are a number of raised grips which your thumb naturally catches on. 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.

Providing you then have the app open on your smartphone or tablet when you go to clean your teeth, the built-in microphones will listen out for the sound of the brush. 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.Take a look at the lower third of the brush find the battery power icon, above which is a small amount of branding, which is barely noticeable, embossed into the rubber. 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.

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. You will struggle to find a cheaper electric toothbrush than this that offers performance and quality. At the end of the 2 minute cycle, the head will again change its oscillation to give another tone to confirm the cycle has ended.

It will last on average 7 days. That is based on 14 two minute cleans or approximately 28 minutes of brushing time.

Speaking from experience I can say that even after years of using an Oral-B floss action head, I noticed the difference with the CrossAction. The clean and the way it brushed the teeth was different. The smaller brush head in comparison to most manual brushes, is scientifically engineered to ensure you get the best clean. Being smaller, you are able to easily reach more areas of the mouth. The addition of the 3D technology which rotates, oscillates and pulsates means that the brush head achieves a motion and cleaning pattern that is just not possible when compared to a manual brush.
