Perfect for Classroom Robotics
Used these for our Level 5 certification course. Students found them easy to program via Arduino IDE. Connectivity is stable and the dual-core helps when running multiple sensors.

Good value
Cheaper than official boards but works just as well for school projects. Shipping was fast. One pin was slightly bent but I fixed it easily.

Great connectivity
Wi-Fi and Bluetooth work flawlessly. Only wish the pinout diagram was included in the box, but you can find it online easily. Good build quality.
