finally a true difference maker toothbrush [SEP] i saw the advertisement and i decided to check this out did not realize how quite expensive it was but i decided to take a chance and boy am i am glad totally worth the purchase price my teeth feels cleaner look brighter and my mouth seems fresher i even smile more after the use of this product and i am one to never smile it feels as if you are getting a professional cleaning everytime you use it not only does this thing brushes your teeth it polishes them also i am actually going to purchase another one so i can have one at home and one at work also for famillies all you have to do is buy more heads because everyone can use this and this thing is totally pain free in fact it tickles your mouth but you will most certainly look forward to brushing the three speeds are very nice plus if you follow the directions and brush in quarters it has a bit of a hesitation to let you know when to move onto the next quarter i find this very useful if you never had proper instructions on brushing this is in my opinion a life changing and habit changing product
