    Replacement blades for Philishave

    Replacement blades for Philishave 16th Sep 17 at 10:12 AM
    My (approx 18 month old) Philishave has decided that it needs new blades (three leds came on) - I have reset the alert by holding the power button for 6 seconds
    But wondered how these devices actually decide when the blade needs replacing
    It cant be by wear (too tiny a change to measure)
    I am guessing that it can't be a clock (too complex)
    Any ideas ?

    Perhaps it can measure the total length of time it has been switched on, and set the LEDs accordingly?

    Maybe it counts revolutions of the heads?

    It might detect the increased workload on the motor (larger current draw) but that's maybe too high-tech for a shaver. A spray with Phillips shaver clean and lube every once in a while might help. The heads on my two previous Phillips shavers lasted 8? years before giving trouble.

    I mean, the motor must turn 3000rpm (50hz) - which for a 2 minute shave - every day for 18 months - will be 3,285,000 revs - so this is obviously the limit of wear for the heads !

    Previous philishaves have lasted a lot longer than that - my first philishave (when I was 16) lasted for almost 20 years - but they had no wear indicators in those days
    I reckon that todays shavers should last a similar time - but it is a con by Philips - trying to "scare" us in to replacing parts that do not need replacing ...
    New blades cost almost as much as the shaver cost in the first place.
