I Believe I Have Discovered a Defect In Design
The upper spindle on which the brush snaps into place appears to be constructed partially of plastic. While the brush is vibrating it rubs against a metal portion, especially when the user is pressing the brush against his teeth. My toothbrush now does not operate. Once even the slightest pressure is applied to brushing my teeth the vibration ceases. If no pressure is applied, as in not touching my teeth with the brush, the toothbrush vibrates as it should. This is poor design for the obvious reason - one has to apply pressure and in doing so the plastic part deteriorates making the electric toothbrush useless. Is this a know defect? Can I get my expensive toothbrush replaced? have you made alterations in your latest version?
