It's well made and very durable . This is a solid ball that will last . It's nice to have something like this that's easy to use, because you don't always have someone to do it for you. This is great. You can find this on Amazon Here
I also received the instructional DVD that goes with this massager.
This instructional video helps you out if you have the muscle massager roller ball. I think it would make sense to sell the 2 as a package deal, but that's not the case. The video is informative. It shows you how and where to use the roller ball. It's easy to follow, detailed and set at a good pace. It's easy to catch on quickly and after seeing it a few times you'll have it memorized. I Did think this showed me more ways to use it than I would have though t of otherwise.You can get the video on Amazon Here.
