excellent!
I bought several of these thermometers to monitor a vacation cabin. Not only to see the current temperature and humidity levels, but to see what is going on when I am not there. Before I leave, I reset the min/max - allowing me to see if there were any freezing temperatures in the house while I was not there. Accuracy was perfect. I compared not only the three that I purchased against each other, but also other thermometers that I own that do not have the min/max indicators. I lined them all up and within a day all were reading identical. I am confident in the readings that I get when I return to the cabin. I'll be replacing all my old thermometers with these.
