Very useful for teaching Python
I bought these for my Python class. They were connect and program even for beginners. I would recommend these to anyone looking to expand their Raspberry Pi projects.

Dirty parts with rusted components
Physically dirty , rust on pins, shoddy soldering
M**S
I returned mine.
Please be aware that the H/L jumper on this item is a tiny DIY solder joint, not a standard pin jumper. Also I had a feeling that I would have issues with the shallow screwdriver slots for the adjustments.
