DO NOT BUY THESE - THEY WILL DESTROY YOUR TOOTHBRUSH!!!
Sadly we have lost two Philips Sonicare toothbrushes to these awful replacement heads. After replacing one toothbrush, we moved house, and I failed to throw away these heads. So when my wife went looking for a replacement head after the move, these were the first ones she found - and destroyed a second toothbrush!<br /><br />The symptom is that the brush gets very loud, and eventually the mechanism fails. This is even after changing out the pisonicleara head for a real Philips head.<br /><br />Whereas my identical toothbrush which has only ever had GENUINE PHILIPS REPLACEMENT HEADS has continued working fine, for several years.<br /><br />LESSON LEARNED: ONLY BUY THE GENUINE PHILIPS HEADS!
