Query: Not the best from La Crosse

I purchased 2 of these in Dec.2010 ( 11 months ago ) These units are not the easiest to read due to the design. I placed one in a mud room the other in a basement workshop. One has stopped working after 6 months ( I tried changing batteries a couple of times - no change , the display fades in & out . The other one is working fine but I had to place it with a backround paper behind it so as to make it easy to read . I need to find a replacement for the defective one but it will not be this model.
