I bought this a month or so ago for a sore shoulder/arm. I love the hidden magnet closure and it's a great size. I turn it around instead of having the long part going down my back so it's draped over my shoulder and down my arm. It's the only thing that gave me any relief.
I bought this for my husband and it is everything I wanted and more. He has a very stiff and sore neck and uses it every day. The wrap around feature for the neck is great.
