I've got every single SOTA product, darlin'. And know how to use them. My fav is the BT7. Would like to start hitting my Mag Pulser again - but have read conflicting accounts as to which polarity to use. Will be using on face (sinus and temples) and lungs to break up congestion. I've read the north side (-) "repairs/rebuilds" while the south (=) stimulates. What might you know?
And when's that new model or yours hitting the shelves, dangit?
