It works but no long term testing done with it.

The si7021 is currently one of the best Humidity / Temp sensors out there in terms of Value for Money. The accuracy it offers along with the easiness of use and the cost of purchase is unmatched from other products. A lot of code samples out there for you to use.It worked out of the box , no issues whatsoever. I bought 5 for experimentation and all of them worked without any issues. Its dirty cheap and does what you want it to do. Just buy it.

Tested this using an ESP8266 dev board, and used the Adafruit library. Got good consistent results over a long period test.

Ok
