Be aware that Electrodragon only sell counterfeit versions of all branded products. Their general noname components are fine though and the company feels quite reliable. I have purchased goods from them several times.
I've reported their "Arduino" boards to the Arduino staff before and all that happened was that Electrodragon renamed them to EDArduino on their web page. I haven't purchased any boards from them but I'm fairly certain that they're just regular counterfeit clones and that they all carry the Arduino logotype and are branded as Arduino in reality. Don't buy them.
