So I finally got a thermostat and it seems to be a little bit off. It's reading at 89.6 right now and my thermometer is reading at 86.7. I'm not sure which one is correct? I'm thinking the thermometer is to be honest. But I do like the thermostat because it regulates the heating pad. I set the high to 93 and it's supposed to turn off when it gets there and turn back on when it gets 2 degrees lower than that.
