content: I had one similar for many years that was accurate until someone's dog jumped up and knocked if off the fence breaking it. I bought this to replace it, however, I can't imagine how this can't work unless it is made of really shoddy materials. It reads way off the correct temperature as told by my radio controlled weather station.My advice - don't buy it. The manufacturers will get the message eventually and make a decent product. As long as we are buying and putting up with shoddy goods they will keep producing them making us part of the problem!!!
