Hard to find code examples
Module works but documentation is light. Had to search online for the right library examples.

Accurate and fast
Tested against a calibrated thermometer. Close match and response time is reasonable for the price.

Works great with STM32
Used it for a climate monitor project. Very stable readings and easy to interface with the Nucleo board.

Good value
Needs external pull-up resistor sometimes depending on your setup. Otherwise works as expected.
