Well, the glue they used to hold on the headlight lenses sucks. Majorly.
I've lost both of my headlight lenses because the glue cracks and separates from the plastic. The lens drops off and can be gorilla-glued back on, if you catch it in time and can find the lens. If not, you have to buy the entire headlight, which costs anywhere from $80.00 to $150.00, depending on where you get it from.
