The device arrived in reasonable time, and a query was attended to promptly.
Over the course of two tratment cycles my achilles tendinopathy improved greatly, with the swelling in the tendon much reduced. Results elsewhere were less spectacular (a full-thickness tear in the supraspinatus muscle in my shoulder was a difficult one!) but there were modest improvements, and in no case did the condition being treated get worse.
[I am enthusiastic about the product, but I am trying to be objective]

Approximate cost: $500
