Product review (5 stars): Simple and easy DIY replacement
Does exactly what it's supposed to do.

Replacing took exactly 5 minutes:
Simply unscrew the 3 hex-screws holding the top hinge, remove the door, and unscrew the single hex-screw holding the hinge piece inside the door. You might need to wiggle it loose after unscrewing it.

Before you buy this, make sure the other half of the hinge is still in good condition, if not you should consider buying the 2nd half as well.
