SHOULD BE A MINUS 10!
I had this product and for one month it worked. Then it stopped working.  I contacted the company and after many tries was told to "copy and paste" this form...take a screenshot of the mat...and on and on!  I informed them that I am 78 years old, not computer literate at all, other than to e-mail. I don't know how to copy/paste and don't even know what a screenshot is!  They did not seem to care and continued to tell me to do those things.  Finally, I just returned it to Amazon and will never purchase a Relaxzen product again!
