After 1 year of light use, the card leans to one side. (It has a permanent list when the boat is level). Intermittently sticks on incorrect heading. This is a front reading compass, but the night light cannot be positioned to adequately illuminate the front of the compass and lubber line.
I like this compass a lot. Easy to read, clear markings and steady movement. Don't cheap out on a compass. A good compass like this one is an instrument that you can depend on.
