I have been using (Zapper/Biotrohn) every night before bed for 12 years. I can say that I fall asleep very quickly and sleep deeply. First time I used Zapper for Oxiuros worms. In the morning the toilet was full of little worms… it was amazing.
The experience with the Biotrohn is fantastic, with so many solutions for all kinds of health problems. Recommended for every home in the world.
