Today my Beurer 30 arrived! The first impression is good. It seems stable and works fine. (However, I first had to buckle, as I do to the battery compartment is come- simply press device still front and pull out O) Now I'm already in the second session ... and it's fun. It can be set well and tingles now ..- to my stomach by the way I work around (if that is not an argument, I also do not remember ...) the device has been properly KaWuum ... is due to the Intensivitätseinstellungen but something for everyone.
Only of course I do not know .. if it really works ,. But it looks like my abs seem to react already ..... I will again write something when successes are clearly visible or that thing was a bad buy ..- after all, there are 3-year warranty ...!
