I bought one like that. YEARS AGO to control humidity in warehouses. I recently decided to buy two more devices to monitor the humidity and temperature in different parts of my house and thought it would be a good idea to put them all side by side for comparison. RESULTS: In just a few minutes, they all synchronized and showed almost the same values (±1% humidity and ±0.2 degrees temperature). It's actually very good! The color convinced me! To be honest I didn't expect that for this price. Needless to say I am very happy with their quality :)
