Fantastic!
This thing is amazing! I had some really bad muscle cramping in my back and this took care of it. It is super strong and light. It's like they took high strength aluminum and put a hard plastic shell over it. No idea what it's made of but I have several kids who beat the crap out of it and it hasn't warped or deformed at all in 6 months! Perfect shape to get in there where you need it. One of my best purchases ever!
