I am back to the gym recently and have plenty of aches and pains from my absence. I was looking for any means to ease the tension and knots in my back. especially, as well as other places. This little gadget does the trick! Small enough to be portable when on the go, but big enough to work out an ache that ails you, all wrapped up in pink cuteness! I appreciate that it is waterproof, try it in a super hot shower after a workout! It is definetly multifunctional, and will cure whatever aches ail you!
