100 Biofeedback BIO-Squares
Customer Reviews of 100 Biofeedback BIO-SquaresCustomer Review: Undecided
Squares changed color in the "relaxed" area but never saw it get to the "stressed" color. The "calm" reading did not match when a pulse monitor was used with it. Example-When the pulse rate went up the color on the square stayed the same. They are measuring two different things but both purport to measure stress.
