I went to a shop where they were selling the Future 14000DX bio-electric machine and Amlife mattress, which operates on the same principle. (Both companies owned by same boss.) I used the machine there (free) for 3 months, almost daily. It works by increasing your blood circulation, which brings more oxygen to your cells and creating negative ions in your blood, which which is an anti-oxidant. It reduced my fatigue, I slept really deeply and had more energy the next day. The mattress is supposed to do the same sort of thing, but at a lower amount. The single mattress is now RM12k, double RM17k. I dunno whether to buy or not cause didn't try. Because the electricity is lower, you need to use it for 8 hours a day, vs. the machine which you can just use for 1 hour.
