[Q]: Good looking item and hope I don't have to return it, as one of the rings is loose and I received the item in a plastic pouch without the stated manual nor bag posted on the Amazon product description.
[A]: 3

[Q]: I was sceptical that it would relieve pain I had in my knee when exercising. However it worked perfectly and I now use it whenever cycling or walking distance. The velcro is extensive and it is well made. Looks like it should last some time.
[A]: 5

[Q]: Bought it for my spouse, but it would not fit comfortably around his head. He said it was uncomfortable and can't use it. Now I'm using it, and I have to stretch the band out before I do since it gets uncomfortably tight. I would only buy this again if these headbands were in a larger size. I'm petite and it was still tight around my head. Sound quality, buttons, everything else was decent.
