Stable readings

Much less noise compared to older modules I have used. The onboard TL431 reference really helps with stability.

Good value

Works well for the price. The pins are a bit close together so careful soldering is required for headers.

Great for weighing projects

Used this for a kitchen scale project and it worked flawlessly. The SPI interface is much faster than I2C alternatives.
