I purchased this watch for my son at a local Target store two times. Both times, one of the buttons would not work. The first time, we could not set the time because of a faulty button. The second time, the button for the light did not work. My son found this on the Amazon website and we purchased it. He has no problems with the watch at all. It is a great watch for many reasons. Other than keeping time, it has an alarm and a stopwatch. He really likes it.
