Query: Sonicare Elite 7500 Toothbrush

This is my second Sonicare Toothbrush the first one lasted for five years of daily use. The new 7500 is much lighter and smaller which makes it easier to use and more effective in reaching all the surfaces of your teeth. I'm very pleased with the product and how well it removes plaque and food bits from between the teeth. My dentist always remarks about how little tarter I have during semiannual check ups and cleaning. I highly recommend this product.
