Query: poor customer service

I have bought three of these, two as gifts.One of those bought as gifts (for my father-in-law, naturally) died in less that 6 months. The LCD flickers, it cannot be reset, will not lock to the signal, and reads the temp neither indoors or out.When I contacted the email listed on the back of the clock, I was told that they no longer made that model and would not replace it. No other contact info is available.As an Engineer, I am highly offended by the idea that you can make a defective product and then eliminate any warranty returns by simply not making it anymore. By the way, they make the identical clock except that now it has the phase of the moon. Same clock, same price, no warranty.Cool idea, neat clock when it works, but buy from a more reputable company with actual warranty protection!
