What kind of warranty do the Chinese give you if ordering directly from them, and what kind of support? It's good you noticed the criss crossed wires on your bluetooth dongle but most wouldn't have a clue including me. I was happy to pay double for my Overkill for the peace of mind and the warranty which no one has matched so far.All of that is something for the entrepreneur to figure out, not for us the end consumers. The current market for the exact same hardware is out of stock from Overkill at $120+ or from China in stock with long shipping times at under $60.
To me doesn't matter much. I'm happy buying the same hardware from overseas at half price, solder my own screw terminals and fix their wiring mistakes. But having more options to buy the exact same hardware is always welcomed.
