agine, never buy a thermometer again! Have you noticed the stick on, dial shaped “reptile” thermometers are accurate to about +/- 1000 degrees? I haven’t seen one yet that was even close or that lasted more than 6 months. Buy just three of them and you could have spent the same money on one of these! Once you have it you will wonder how you lived without. A basic temp gun is the best investment you could buy for the smaller scale reptile keepers.
