Hey fallenangel, yeah, I would love to have one in a small receiver that rolls under your arm pit to give you an estimate of your mone production, at rest, after a work out, etc! Roll it on and, beep from the little speaker with a LCD screen pop showing* your running on 2 sprays of natural A314… *recommend using only socials unless you want to get your @ss kicked!!!
Unfortunately, not so portable or economically feasible!!!
