Very good instrument
Best in class Use this thermohygrometer in many commissioning tests. Aside of a high accuracy, the online data capture and basic reports that can be exported in ccv format, makes this instrument a good option for field testing.

Accuracy seems to be great
I wanted something I could use as an easy humidity standard. This unit had the best specs for the price. I bought it despite the drawback that it had no visible meter and needed a smartphone to display the readings. Turns out the smartphone requirement was its best feature. It will display a real time graph of the temperature and humidity readings. You can use the graph to see when it stabilizes, plus it will show you the fluctuations in the humidity and temperature. Since I'm using it for a humidity standard, couldn't calibrate that. I did calibrate the temperature readings against a lab thermometer. They exceeded the claimed accuracy. The difference between the readings of this instrument and the lab thermometer were essentially nil.

Works great and connectivity it’s seamless
Turn on and throw it inside of a refrigerator you’re temping down and checking cut in cut out temps on and don’t have to worry about opening the door to check on it just download the app and see everything on your phone. Bluetooth distance is further then I thought it’d go. Also batteries last pretty long as well
