Bought base and 2 other sensors. Love that the sensors are waterproof and hung one outside. Keep base next to my chair so I know temp in main living area, 1 in incubator as a double check and 1 in my quail room to keep track of temps in there. Temp is a bit off from other thermometers I have in incubator but within a degree. Could be because it sits on floor.
