Review on Relieve Tension With GOHIKING Trigger Point Massager Tool: A Handheld Solution For Neck, Back, And Shoulder Pain by Robert Hoge

The instructions are really just pictures that do that explain much. This back massager is weird to use because it is hard to find an angle. I also warn to be careful while using this to not hurt yourself and make sure you do not push too hard and you know what you are doing. 20 dollars for some plastic is a bit much, but this is durable and a good weight. If you do some research on how to use this, this might be a good product for you.
