    Good enough
    5 Stars
    Good enough
    Was looking for a digital Thermometer for when I soon evacuate & recharge my vehicles A/C. Wanted a Probe model to insert into diffuser. This should do well. Tested against two other Thermometers with less than 1°F diff. ( see pix). So, the probe is sensitive enough where Temp. changes very quickly,( with 1/10 of a deg), however, it took a few min. for the final actual temp. to display. Another reviewer stated an " old school" trick is to remove the F/ C jumper then place bk at a 90° angle to one pin so as not to loose the jumper. Don't do that, as it won't fit, because hole there, not Lg enough. USB pwr supply just fine as vehicle has that. No batteries to ever worry about. Unit powers On/Off with USB connector.
