Review on DonJoy Performance WEBTECH Support Strap by Robert Howell

Two sizes are described: S/M and L/XL. If your knee is the same as mine and in the 15 inch upper limit for an M strap, don't order S/M; I received an "S" for being marked as such, but I was able to return it and get a larger size. The L/XL size marked "L" is larger but fits the job well enough. Please select a larger size when ordering. Pain and facilitate rehab/physical therapy efforts much better than many competitors. This is a good product and they have responsive customer service.
