Review on Philips Sonicare ProResults Replacement HX9023 by Julia White

Except for the overpriced they are perfect. They follow the business model of HP printers. HP sells the printer cheap and pays to replace the toner. Sonicare sells a relatively inexpensive toothbrush handle and makes money off replacement brushes. However, Sonicare is the best, so it's almost impossible to get around. There are aftermarket brushes made in China that fit Sonicare and I tried them once. They were obviously worse, so I went back to the original. Buy in bulk to save as much as possible, and remember there are no shortcuts when it comes to taking care of your teeth.
