Query: piece of junk

Well, I was looking for something to let me two-year-old know when he could get out of bed in the morning. The Time Tracker is a great idea but poorly designed! First of all, like others before me have said, it's a hassle to program and it only holds one time setting. So you to reprogram it if you plan to use it more than once a day. Then, the biggest frustration is that it locked up on me after two days of use. My poor son waiting patiently for the light to turn red and it never did. A good idea! Poor design! Low quality! Overpriced!
