Claire M. ★★★★★

Finally getting all 16 channels wired up for my sensor array took about ten minutes, and the dual-bank power split means I can run 3.3V logic on one side and 5V on the other without any level shifting headaches. The expander handles PWM and interrupts cleanly, which saved me a whole microcontroller.

David L. ★★★★★

Was running out of pins on my Arduino for a keypad plus LEDs, and this gave me 16 more without touching the ones I had left. The dual bank split is handy since I could keep the LEDs on one side and the buttons on the other.

Robert M. ★★★★☆

I used the dual-bank power feature to run some 5V sensors alongside 3.3V logic, which worked perfectly once I read the datasheet. Took a bit of configuration to get going, but the extra 16 pins really saved my project.
