It has a one year limited warranty. It applies to "all defects encountered in normal use." Then it gives a whole long list of things they don't consider normal use. The print is very tiny and it's a lot like reading those sheets of paper that come in drug packages.
It gives you the option to purchase a warranty that covers basically all damages such as drops, water, etc. I believe it is for a year or 2, but I ended up not getting it because it was $40 to get the protection on it, so I opted to just try to be careful with mine.
