Product review (2 stars): Only worked for two weeks
I used this device for measuring heat and humidity in my reptile's terrarium. I had this thermometer for about two weeks before the it stopped working. The numbers on the screen stopped showing correctly and I couldn't read any of it. I made sure that this device did not get wet while it was in the cage. I tried switching the battery but that didn't help. Very sad about this outcome because the first two weeks I had it,  it worked very well and was exactly what I needed.
