I put mine through the washer and dryer, and after a week of drying it worked fine. Those things were indestructible, too bad I finally lost mine on an airplane.
man I love my shuffle for this..I bought it like 3 years ago and its still in like near pperfect conditions after falling on it skiing, it falling in water, dropping it many times, stepping on it after dropping it..it barely has a scratch
Mine just stopped working one day. No reason. It just gave me what is now called the Traffic Light Syndrome (lights blink for no reason) and cant be fixed. Fucking beat. It was so rad
