I have had two of these Oral B Vitality Sensitive toothbrushes.  The first one lasted quite well, for about two and second less well, only for about 18 months.

Looking online these electric toothbrush cost about £17-£20.  I bought my first one when it was on offer and seem to remember it was about £12, which was part the reason why I got it.  I wanted an electric toothbrush, but not a really expensive one as I couldn't see the point.

The toothbrush comes with a charging lead attached to a stand the toothbrush sits in. This lead plugs into the shaver socket - it is a two pin plug.  I often charged mine outside the bathroom so had to buy a converter plug to use with it.  To begin with the toothbrush charged very quickly and lasted a long time on one full charge, around a week.  As the toothbrush got older it needed charging more often until it basically needed charging all the time.  The second one of these I had needed charging after every clean before it was 18 months old, which got very annoying.  Then by 18 months it wouldn't charge enough for one clean, no matter how long I let it charge for.

There is a two minute timer on this toothbrush, although I always ignored it and therefore the timer got out of sink with my clean.  After two minutes the toothbrush makes a sort of "jerk" vibration out of sink with thr normal motion of the brush, this is how you know the two minutes are up.  It's s good idea for kids but I don't feel that for adults it's necessary, I just clean my teeth as much or as little as they need.

This toothbrush comes with one spare toothbrush head.  I usually bought replacement heads when I saw them on offer at about £4 for four.  I think you can buy other style heads in the Oral B range as the socket for the head is the same on other Oral B toothbrushes.  I like the head of this toothbrush as the brush part is small and round, about 1/2cm in diameter, allowing it to really get it to my back teeth which is really good as I have wisdom teeth ehich are very hard to clean eith bigger toothbrush heads. The head pulsates and vibrates to shake plaque loose and brush it away.

The on/off button is on the main handle of the brush and lies under your thumb as you brush.  The switch is under a sort of rubber covering so water can't seep in.  The brush is therefore very straightforward to use.

I really liked this toothbrush, hence I bought another when my first one died on me, however I was really disappointed with the life span of the second one and since it broke I have gone back to using manual toothbrushes.  This experience kind of put me off electronic toothbrushes!

I therefore am only going to give this brush 3 out of 5.
