This toothbrush takes some getting used to and is quite different from the Oral B ones that I normally used. These toothbrush heads are tiny compared to the Oral B ones and even smaller than the Oral B heads that have an extended brush length. Having said this it's not always size that matters but performance. Like most electric toothbrushes, this one has a timer to let you know when to move on to a different part of your mouth so that you have an even clean. It also has a 'clean and white' setting which gives an extra 30 second blast of cleaning. They state that you can see the difference in 2 weeks but we'll have to wait and see if this is true. I have to say that when I first cleaned my mouth, the shaft tickled my mouth with every movement which was funny and annoying at the same time. Although the toothbrush head seems much smaller than the Oral B one (and definitely softer as well which isn't necessarily good) this also means that it can potentially reach parts of your mouth that an Oral B might not. The toothbrush head also sits at a slight angle on the handle too which also helps reaching hard parts of your mouth. I did like the travel charger though as the unit opens to allow you to reel in excess cord. The 2 toothbrushes also come with a travel case that holds one toothbrush unit (but 2 places to carry toothbrush heads - I guess the thinking behind this is that if you travel with your partner, you can just swap heads (no room for the charger unit though which would have been an additional bonus and at the price it costs maybe it should do).
I found the Retail price far too high for what it was in comparison to other electric toothbrushes, but i guess it is a completely different way to clean your teeth. It doesn't work in the same way as normal toothbrushes - although it does a scrubbing action, it also works on new technology too as the bristles vibrate at an intense rate (about 30,000 times per minute).
