Best classroom kit

Using this for my robotics class. Students grasp the logic faster with visual blocks. R4 compatibility is a plus.

Missing jumper wires

Kit was mostly complete but lacked enough male-to-female jumper wires for all projects. Support sent more quickly.

Great hardware, software needs update

Love the components included. The visual programming software occasionally lags on Windows 11.
