Not too bad, but not perfect

Does its job, doesn't get in the way. In bright light (e.g. direct sunlight) it can be hard to read the screen. The "lift wrist to show time" function takes a second or two to display the time and sometimes doesn't work which makes you look like you're just trying to learn to tell the time.

The pairing with my Android didn't work immediately, had to do some googling and take specific steps to get it to work.
