I had an acute pain on the inside of the elbow, in a spot that I could barely touch. The same day I received the robot, used it for 2 times 5 minutes and the next day, the sore spot had disappeared! Of course the lingering pain was still there, but the spot that I could not touch was gone! Believe it or not! Also the reminders you receive twice a day plus the e mails makes you think that it is a Spy Robot, albeit a good spy… had an amazing chat with Lori today, and she dedicated 45’ to fully explain options, treatment, etc. Those people are on a mission to cure elbow issues, one patient at a time. Great purchase! 👏👏👏
