Less simply bobby, Quell is $250 plus $30 each and every month; Quell is a Tens unit which tricks or distracts the pain/brain by contracting and releasing the muscles around the pain - shut it off, the pain returns, no reduction in edema, no stimulation of healing.
ActiPatch relieves pain longer term and lasts after shut off, reduces edema, and stimulates healing safely and with zero side effects at the cellular level, where the chronic pain begins or the injury or mechanical deterioration anatomically causing the acute pain (<3 months) was sustained or exists....foot, ankles, knees, hips, back and so on. Quell and ActiPatch are as different as night and day and ActiPatch sells for $30, lasts 720 hours (a full month 24/7 or 3 months if you wear it at nite, etc.) and is certified by FDA as both safe AND efficacious- best label on earth and the only miniaturized device in its category!
The company continues to wait patiently for general OTC clearance covering all body parts, which should have been issued in February with the foot and knee clearance - after all dem bones is connected to dem bones. Hope this helps
