Query: 3 Month Warranty -- for a reason!

Purchased clock at Christmas. Projection didn't work -- after much time on phone waiting to speak to someone, they exchanged clock -- cumbersome return process -- but in about a month got a new clock. Now eight months later the projection stopped so I called Oregon Scientific to learn how to replace bulb or? Answer was the "warranty is three months and we can't tell you how to change the bulb?" Obviously I was amazed and asked how I could then return the clock to working order and was basically told that I was out of luck. Clock is a nice idea -- perhaps someday, someone will build a quality one!
