Bests & Worsts Reviews from Amazon

Purchased this for my girlfriend who suffers with shoulder / neck pain and complains about it. I was pretty excited about giving it to her for her birthday because I tried this in the store and it felt amazing. I knew this would bring her suffering to an end. However, much to my surprise, a disappointed look came upon her face. She didn't like the gift because it wasn't, in her words, "sentimental enough" :O I thought "WTF?" and ended up having to return it in exchange for a ring which doesn't do anything to bring relief to muscle aches. Go figure, smh.... Before returning it, my wonderful, appreciative father tried it (who also suffers with aches and pains). He absolutely loved it and decided to buy one. He is constantly using and raving about it (I don't blame him because it feels awesome). Also, he owns a very expensive massage chair but uses this more often. Anyway, my sister tried his and loved it too. So now she has one :) I now use their massages to relieve the headaches I often get today from hearing my girlfriend complain about her shoulder and neck aches, which she has no relief for because my "thoughtless" gift had to be returned. Now, whenever she complains of pain, I tell her to go massage herself with that ring :/
