This thermometer measure anything but the correct values within my terrarium. Again and again I experienced deviations from ten, twelve and even 15 per cent compared to figures of comparison devices. Although the suction cup held surprise well, but hid the view of the measured values. These were, however, after a few weeks of use anyway no longer to read because the device extremely sensitive reaction to moisture - a mockery at a device that is supposed to have been designed for use in a terrarium. Conclusion: The money for this I would have been better presented.
