Works but needs config
Remember to enable internal pull-up resistors in your code. Once configured correctly it works fine, but beginners might struggle.

Solid Build
Keys feel clicky and responsive. Only reason for 4 stars is the silkscreen could be slightly larger for easier reading.

Compact and Clean
Fits nicely on my custom PCB design. The mounting holes are well placed and the overall quality exceeds the price point.

Perfect for Prototyping
Used this with an ESP32 project for menu navigation. The tactile feedback is excellent and the pins lined up perfectly with my breadboard.
