Title: It tells time . . .
Review: I purchased this about a month ago. It started off working fine. After a few workouts though, the display locked up. For some reason I can't explain, it unlocked itself and continued working again . . . until the next workout. Halfway through the workout it wouldn't let me switch to the heart rate monitor mode. It tells the time still, so I guess I could use it as a cheap watch, but I can't change anything on it and the most important part for me is I can't access the heart monitor part.
