I think the Compression Shoulder Brace with Pressure Pad is an excellent purchase. I've been experiencing shoulder lock with some particularly severe pain in my right shoulder, even causing me to lose sleep. As soon as I received the Shoulder Brace in the mail I tried it on and it worked instantly. I couldn't believe the drastic change, I even wore it to bed and it helped my get through the night without pain, the first in a very long time. I wore the Brace all day yesterday but removed it for sleep last night, here it is the third day and not only was my sleep much improved (even without the Brace on) but I haven't needed to put the Brace back on today. When I feel the need I will put the Brace back on. My only complaint, and the reason for only four stars, is that the velcro attachment for the arm is uncomfortable, it's plastic and tends to scrap the sensitive back portion of the arm. A small complaint about a device that is well thought out and actually works. I highly recommend it for shoulder pain sufferers, it will work on either shoulder and is very easy to put on.
