Title: Planned obsolescence: Avoid
Review: These brushes work fine, but the total operating cost is high due to planned obsolescence of:(1) expensive brush heads wear out fast, and(2) the little rubber blue-green on/off button wears out after about two years of use, leaving a gaping hole in the device handle, which causes the device to fail if exposed to waterThis is a known quality control issue that Philips chooses not to address.
