The very first brush head from the pack ruined my Philips Sonicare. The delivered brush head is so firmly on my toothbrush that when removing the brush, the holder / pen for the brush head of my Philips Sonicare with torn and was stuck in the brush! Bracket / pin could then be removed with tongs from the brush head. The rubber coating on the pin / bracket my toothbrush broke it. "The Good" has indeed paid me the money for the brush back immediately, but my Philips Sonicare is no longer usable and there was me a damage of 79th
