These easy-grip massagers (two per package) are great for taking the load off at the end of a long day. While you can use alone, at least for those places you can reach, it is always infinitely better with a friend. Nothing like feeling the both of the sliding up your back, easing tension at every turn. Using the Happy Heart is better for the massager, too, as it saves on finger/hand wear and tear. Tips on back of the package, heats up for that extra relaxation and is easy to clean. Even works on your pets!
