I bought the device DeVita Ritm after my sister bought it. She has 4 children (3, 7,15,16 years). From December to April, it is not bought any pack of pills! Children during the winter colds and viruses treated device. She says she is grateful for what he copes with the cold, so as soon as it was a real problem. I bought the device for the treatment of asthma. In the autumn there was a strong complication, but when it bought the unit and in the winter on a background of viral infection asthma started, I began using the devices to manage successfully without pills, and I believe I can handle this problem! Many thanks to the staff of the center for help and advice. Thanks to the developers of these remarkable devices !!!
