ProtectPro Solves Monica’s EMF Sensitivities Monica found ProtectPro’s cellular device to take care of her sensitivity to emfs. She was having a numbing and tingling sensation in her fingers everytime she used her cell phone. Protect Pro works by harmonizing negative frequencies to positive ones so they are no longer harmful. Though we cannot see frequencies, we can experience the difference in how we feel around them and the ProtectPro device can be muscle tested to show its efficacy.
