I really liked the product at firsty, many convenient features. But below -17 degree celcius it will display LL.L wich mean it is too cold to read... In my region we will often see -30 so.. what good is a thermometer that cannot resd below -17...... Strangemly the sensor itself is able to read the cold temp if you look directly on it. I will keep it anyway but, im dissapointed,
