Your local customs are entitled to confiscate this as it what is known as "passing off".
it is not actually labelled as "Arduino" nor with their logo
The hardware reference designs (CAD files) are available under an open-source license, you are free to adapt them to your needs.
The Chinese stuff I have bought on eBay has all been fine. Works just like Arduino, only cheaper. I don't buy anything that says it's Arduino if it's not - that's just rude.
Just FYI on the arduino team invented Arduino IDE, half of it is original Processing IDE and the other half is AVRDude with some Wiring (Wiring project that predates Arduino project). The Arduino team is responsible for the third half LOL Honestly I can't tell if the Arduino team invented the file combining (could have been Processing) or command line code for AVRGCC (could have been Wiring). They did design the board but then I'm not sure how much effort on the bootloader. Correct me if you have a better understanding but the Arduino team didn't create everything the "Arduino" stands for.
