Review on 🌡️ KeeKit Indoor Outdoor Thermometer: Digital Hygrometer Gauge with 3 Wireless Sensors for Home, Office, Restaurants, Bars, Cafe - LCD Backlit Display and Min/Max Record by Jennifer Scott

tl;dr: Probes 2 and 3 were 2º (F) higher than Probe 1 and Base. Not perfect, but I'm satisfied. I'm most interested in time differences between areas; it works for me.--Full Story: After a few days of use, I suspected that some readings might be wrong. I placed all 4 components on the bedside table. I waited a few hours to adjust to room temperature and saw that the base station and sensor 1 matched room temperature. Sensor 2 and 3 also agreed with each other, but not with sensor 1 and the base. This discrepancy has not changed for 4 days. Two and 3 show high values. I'm pretty sure sensor 1 and base are close to accurate. Sensor 1 matches my indoor/outdoor SkyScan temperature. I placed sensor 3 outside and this reading seems to be a few degrees higher than it should be.
