  • Heart Beat Detector Keychain

    posted by syworks on 10/26/2007

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week


    Light weight and easy to use.


    Too big to be a keychain. It took quite some time (@15-20s) for a readout. The reading not really accurate. The alarm sound is rather soft (same as those digital watch).


    Buy it if you got additional money to spend.
