Had the device compared with only 3 different analogue thermometers and differences of up to 10 ° read a review by my thermometer gave the following values: Trixie: 36.2 ° C, thermometer: 36.8 ° C So I think that the thermometer at least is relatively accurate. The hygrometer I could only compare with my expensive electrical Raumentfeuchters, deviation of 10%. Unfortunately I have no other hygrometers this from Trixie is here and so we can only hope that this reasonably well, yes'll see if my delicate exotic animals survive ....
Oh, when the package is opened is equal to the retaining clip dropped on the unit, have it with a wire range again tinkering.
