Review on Authentic Philips Sonicare E-Series Replacement Toothbrush Heads, Pack of 2, White - HX7022/66 by Kim Bell

You pay a little more for genuine replacement brush heads but it's still cheaper than buying from BB&B etc. Your reward is over Fake Brands is a toothbrush that is pleasant and quiet to use. I've used alternative brands before and the sound was terrible - waking the dead is annoying. A problem, of course, when your baby sleeps in the hallway. The difference appears to be the size/orientation of the magnet at the base of the head. Until someone figures out how to fit Sonicare heads, don't waste your time trying to save a few bucks.
