Thermometer working, already with a battery. How much correctly I do not know the temperature. Check, add feedback.
Corresponds to the description, the battery is included. It took a long time, everything. Excellent for such money! Temperature is not accurate. 36,3 instead of 36, 6 .....
It's on time. Tracked normally. Packed so-so. Came immediately with a battery inside. I measure the temperature of the armpit, shows that 34,8 to 35,6. Measured a couple of times in the mouth, stable 36,4. So it seems to show quite accurately.
