If you have company over, just beware that some of the knobs may look a bit... suspect, haha. I used my Back Buddy once while my friend Stacy was in the middle of telling me a story, and she couldn't take me seriously/stop laughing. But then, another friend told me a lady at her work even uses her Back Buddy in meetings. They're so awesome. If you rate shoulder rubs up there next to pizza and puppies, I'd highly recommend it! And for under $35, it's very affordable.
Have you used one? Would you give it a try?
