Excellent condition Plankpad Pro balance board - $50 (Ellicott City)

I have an excellent condition Plankpad Pro balance board that I'd like to sell.
The board only rotates along one axis, and is excellent for doing planks.
An accompanying app contains games that can help with exercising while using the Plankpad.
Currently over $100 on Amazon--reference link: https://www.
