What is Reddit's opinion of Jumpers Knee Strap (EA)?

From 3.5 billion Reddit comments

I had jumpers knee and needed a strap to finish off my season. I ened up getting one of these which was awesome https://www.amazon.com/Mueller-Jumpers-Knee-Strap-Orange/dp/B000F5SXJA/ref=sr_1_3?ie=UTF8&qid=1474167425&sr=8-3&keywords=jumpers+knee

I use these knee straps: Mueller Jumpers Knee Support Strap. There is an Amazon link below. I have used this strap for many years with good results. I started using these for playing tennis, and continued to use them when I bike and now OTF. I had so much pain in my right knee (because in tennis I would push off my right side to get to the ball) that I could barely walk. I experienced the same after mountain biking. Since I started using these straps, I have not had any knee issues. I also power walk at 12 incline 4.0 speed for push phase, and run at 6 incline 6 speed for all outs. What works for me might not work for you .. your situation might be different .. but worth a try for few bucks.
