They are a result of Space travle many years ago. The human body can not live in space with no gravity, the body is like a sponge and with out gravity it will expland and die. So internal zappers were created, the shock every 3 seconds and this shock exercises the internal organs and keeps them firm and allows for space travel.
The side effects are ENORMOUS, worms die, waste expelled, diseases dissapear, etc. So may side effects that over 20 such zapper designs were created for human health. You swallow it, it look like a silver pill and it comes out the bowel 12 -72 hours later in general. It is used after surgery in many countries because it immedietly restores the intestinal muscles to normal, etc.
I quit selling them only because they must be imported from Russia and we decided to import nothing and export nothing, but I still hold the Russian Zapper as the ONLY electronic device I would use.
