Works well!
I purchased this after having benefited from this at my chiropracter/accupuncture practitioner's office.  Very cool gadget!  I have found it very helpful in relieving sinus symptoms due to allergies.  I recommend this to others and wish I could find more information about it.  This works as described (it can locate points, and provide a positive or negative stimulation of variable frequency and intensity).  I only wish that there was a headphone port or a volume control knob for the &#34;beeping&#34; that locates points, so that I could use this without the loud beeping.
