These are pretty cool mini boards! I followed Digispark's instructions and everything worked as expected on Win10. However, one of my three boards was DOA. The price is low enough, I can only get some extra accessories, but consider what you want. Please note that there are technical differences to the full size Arduino. From my experience with them, the output current is lower (even though the datasheet says it's the same?). Also, some Arduino libraries don't work or compile, e.g. B.Servo. However, the Digispark Libraries provide a version that works.
