The potential danger of EMF protective pendants, dots and devices?

I used to get very tired after working with computer for 2 hours but wearing body shield, I could continue working on computers for longer hours without fatigue.

I bought EMF home shield and also body shield. Ever since using home shield for home use, my children sleep better and waking up more refresh the next day. The body shield was amazing for me as I get more fresh and alert during the day. I am glad to use the products.
