Before I began using the 3D system, my back would start to bother me by Wednesday. Now it’s not an issue at all.
I bought the 3D system because my back was bothering me. I have worked off a screen ever since. It was simple to adopt. The learning curve was less than what I thought it would be. I turn it on and use it. I have not had any issues.
The learning curve was quick for me. I felt comfortable after two cases and got used to it after a couple of days.
