Great Toothbrush ..................

Having purchased and used a Philips Sonic Electric Toothbrush previously which eventually stopped working, I liked it so much I decided to order another one, albeit a lower priced one as they are rather expensive for how long they last. This one was purchased in a sale, so great price. Having used it for a good few months now, would definitely recommend this Electric Sonic Toothbrush, keeps my teeth clean, fresh and seem to be gleaming! If you are able to purchase at a reduced price it is reasonable value for money, at a full price I would say not, plus for what you are spending, they do not always last as long as they should and cheaper to buy a new one than have them repaired. Would highly recommend this Philips Sonic Electric Toothbrush if you require one that seems to look after your teeth and gums, the 2 minute timer is a great asset too.

Pros

Does the job efficiently better than a manual - Easy to maintain.

Cons

Expensive - Doesn't always last - Toothbrush Heads can be costly.
