Title: Not worth the money - higher tech snake oil
Review: Doesn't work any miracles, but it provides a nice, soothing break. Allow me to save you a couple hundred dollars: learn to count your breaths--breathe in to 4-6 beats. Exhale for 10-15 seconds. Do this for 20 minutes and it can lower your blood pressure maybe 10 points (on top). But drop it below 120/80? I haven't experienced that.
