This is a great device to sanitize your phone. I am a scientist and I decided to test the effectiveness of this phone by myself. I performed a swab test before and after using the Phonesoap. Please see my attached picture for results. The top panel shows a swab test from the phone before the UV treatment.You charge your phone every day, but do you clean your phone as much? Your phone has become a third hand you never wash. PhoneSoap 3 is proud to be the first and only cell phone charger that cleans and sanitizes your phone while it charges.
