Great little machine for easing sore muscles. Lightweight and easy to use on the go. http://www.amazon.com/Tens-Handheld-Electronic-Pulse-nkMassager/dp/B007TOJ948?keywords=Tens+unit

I love this amazing little solar light. It is inflatable so it wont break, and has lots of different color settings and modes. It can be operated manually or with the handy remote control. Great for pools, camping or anytime you need extra lighting.
