Where can I find a Genuine Bluetooth Module?

Recently I bought a Bluetooth Module from EBay and found it was a fake hm-10. Does any one now where can I found a genuine module and is verified to work?

Thanks Clayton

I don’t know where to buy real HM-10, but found interesting threads on arduino.cc:
HM-10 ble device not working and How to flash genuine HM-10 firmware on CC2541 (make genuine HM-10 from CC41). Maybe it will help?
