Have this mat (as it did my predecessor here) tried in a shopping center - total supi - finally time a device which also powerfully "real grip" ... :-) After 2-3 times use one notices how the muscles along the spine loose and soft is back! The only drawback: my neck is not massaged - enough for me to degrees over your shoulder (am 1,65m large / small) - have also tried draufzulegen me, but that has unfortunately not working. The mat could be up a little bent, adjusted the spine, or you can set it so! Too bad, because the neck is by working quite hard and tense and urgent need of a massage! Well, all in all, a great device ...
