Query: Crap alarm clock

This stupid clock worked for the first couple days I used it. After that, it just decided to not wake me up anymore. I was almost late to class 2 days in a row because it did not go off, even after I tested the alarm during the day and it did go off then.On top of that, the screen is readable only at a certain angle and the battery likes to pop out.Worthless.
