Query: Defective on arrival

As others have said, the best thing about this clock is that I was able to see the huge numbers without my glasses. It's also nice that the time is automatically set out of the box. I did find the numbers to be a bit too bright though.The real problem is that on arrival I noticed the numbers on the clock were flickering a bit. Not too badly at first, but definitely noticeable. In the middle of the night, the clock woke me up by making a high pitched whining noise. I pulled the plug and returned it the next day. At least the return was easy, and I bought a different clock that I ended up liking better.
