Touch free hand dryers are the most popular bathroom accessory being used today. For many years, people were satisfied with the push button hand dryer. These days, many are opting instead for the touchfree hand dryers that require no touching with the hands that you just cleaned. This is the main disadvantage to the push button hand dryer. With so many people using public restrooms, who wants to touch the same button that hundreds of people have touched recently? It isn't just a matter of sanitation; it is also a matter of convenience.
