Product review (3 stars): Alright from what i can tell
I ordered two and was excited about the first couple of reviews raving about the accuracy; I compared these to the digital thermostat in my house and only one was close. I expect my house thermo to be off but was hoping these two would be more accurate. they were 3 degrees off in temp; humidity was 3 off from each other and I am just hoping they are only 3 off and one of them is accurate. They are always consistently 3 off so I take comfort in that. (Purchased For a new lizard that is really sensitive to humidity and a narrow temperature range). If you are looking for a ball park this is the product for you but if you are looking for precise... keep looking.
