Used in the middle "hostle" (workshop Metallurgy) shock, dust, it is very resistant; listening radio 8 hours of listening mp3 and over 12 hours non stop. In devanche change the helmet is very bad, buy a-ear headphones (about 20 for a good headset). My first GoGear resisted 3 years before making the soul in a glass of water, it is not waterproof;)
