Recent research from Sweden shows that after just 10 years of mobile phone use, the risk of developing a malignant glioma in the head doubles on the side on which the handset is used. Further research is also showing that the part of the electromagnetic spectrum that is most likely to be the cause of the damage is the 'extremely low frequencies' (ELFs).

CMO (Compensatory Magnetic Oscillator) technology, developed in France and patented worldwide, makes the body dramtically more effective against the negative biological effects of both high frequency (HF) and low frequency electromagnetic radiation (ELF).
