Excellent compression sleeve for tennis elbow issue. Worked wonders on the nagging pain. Size was great and allowed for good compression while the device massaged the critical areas.
I’m not giving this for product all 5 stars due to one slightly annoying thing, taking out one of my batteries. I own two of these so I can wear one on either arms battery is easy to take out of the housing but the other you have to fight it due to the rubber around the edge it gets in the way. Other than that they are amazing and recover my arms very well.
