Query: Horrible Reliability

I saw this thermometer being used on Food Network and I thought it would be really great. First, the pre-programmed temperatures in the thermometer are way too high - probably government recommended temps... Anyway, the first time I used the thermometer was on a prime rib - the calibration was definitely off by alot - I set it at 110 degrees to be on the safe side and the entire prime rib was medium well done when the thermometer beeped. Then, the second time I went to use this thermometer, the entire LCD Screen was messed up and unable to be read. Pretty Much a waste of money for this item. I still want a digital thermometer but from reviews I have been reading, its hard to find a good reliable thermometer.
