I suffer from ostio arthritis in both knees, have been wearing those big wrap-around knee braces and a cane to walk. Lots of pain meds, cortisone shots, glucosomine, etc, all of which help but, still lots of pain to the point that I have to sidle up sideways to get up the two steps that go up to the sanctuary area in my church. Thought I would give this a try on the knee that is worse. Received it yesterday, put it on, and...miracle of miracles.....I could walk normally again! I could barely believe it. I took it off to go to bed and the knee started hurting again. Got up this morning, wrapped this little puppy on the knee again and off to church. No problem with the two steps to the sanctuary so I tried a full set of stairs (gingerly, just in case)..... no problem with the knee! After Mass went to a garage sale that was only accessible by 3 full sets of stairs; again, no problem with the knee that was wrapped in this Kneedit. Just got home, turned the 'puter on, and ordered one more for the other knee!If you suffer from arthritis in the knee, don't even wait to think about getting one of these, just get one, try it; if it doesn't work for you, you can return it but, if it does for you what it does for me, you will be telling everyone you know about it!!!
