Good product. It pinches a bit at the top of my arm and tends to fold on the lip if I am using my arm in a normal range of motion (say buttoning up my dress shirt), but I just fold it back down and I'm fine. I have been wearing it a couple weeks to alleviate the pain from tendinitis in my elbow that I have been dealing with for over a year now. This has almost totally eliminated the pain. There is still a little bit left so I will continue to wear. But follow the basic guidelines of wearing no more than 8 hours a day and never over night and you should be fine.
Their Customer Service is spectacular. Fast and complete. They took care of a problem I had with a seam tearing on one of my sleeves by immediately sending me a new sleeve no questions asked and without me having to send back the old sleeve. Very cool.
Got these for my mom since she is so prone to sunburn and they work great. It always does the job of making sure she doesn't burn. I would buy again! A little snug but they stretch to fit your body type quick.
