The first ones I met were defective. They sent it back and sent new ones with no problem. The worst thing about thermometers is the loud beep every time you press a button. I accidentally dropped one and it fell apart. I realized I could turn off the beeper, so I cut off one of the wires leading to it. I was able to reassemble the case and the thermometer works without a beep! There weren't many thermometers that had a max/min function with dual temperature readings. Those were the cheapest. They suit my needs (hydroponic/grow box).
