Product review (1 stars): Killed my birds.
Extremely innacurate. Cross-Tested it with other proven thermometer/hygrometers and the reading is more than 10% and 10F off. If using to incubate eggs or for a terrarium, this disparity is enough to kill your animals. On top of all that, Amazon recommended this under the description of "Most people keep this item, it has a lower return rate than similar items..." Well that's because you CAN'T return it. For some reason beyond me, this item is ineligible for return, even if its broken or defective upon arrival. Beware, and DO NOT BUY.
