The display is large and easy to read. Accuracy of thermometer and hygrometer seem to be quite high. At least the comparison with other devices in the house are not too large Abweischungen. However, the TFA 305011 is noticeably faster when updating as our other thermometers and hygrometers.
We find the TFA 305011 so good that we have already ordered a second, so we do not ever have to change from room to room.
