We just got an LG still air - yes, I know, I know, it is a "murderbator" - we're planning on altering it to make it more reliable. But it was a really good deal and I couldn't pass it up. I have it plugged in, trying to check the temp levels. It has the little glass thermometer that it came with, as well as a digital thermometer/hygrometer that was my son's. The glass one says it is a little over 99.5 (where the line is) but my digital one says 98.9 - which one would be more accurate? Does it matter since they are both so close and within an ok range?
