回答“Tip loose and broken off(?) possible to fix?”I’m so annoyed with Philips. This toothbrush cost me a small fortune. The metal shaft came out with the toothbrush head when replacing it. There’s absolutely no way of getting this toothbrush open without damaging it despite what has been written above. Look at the YouTube videos and you will see that they’ve destroyed the metal end cap and/or rubber seal in the process of opening it. I can’t believe a toothbrush that costs this much can just fall apart. The best resolution to this issue is to buy Braun. Never had a Braun fall apart on me and also the toothbrush heads never made that ridiculous loud noise that some of them randomly make, even brand new ones.
