Perfect for taking the temperature to enlightenment

Purchased temperatures to track my awakening (Symptothermal method). I just made a little test, taking my temperature three minutes apart, and after two minutes apart. The measures ranged from 0.05 °, largely accurate enough for my purposes.

The thermometer is light and thin. Attention: to take the morning temperature must not rely in the first temperature signaled by the beep, otherwise wait two to three minutes. The volume of the sound signal is very low, a not to wake the person next to us.
