I am not familiar with the "Hacker" brand, but I have seen many brands that are compatible with HW programming cards. This has led many to believe that HW is the OEM and rebrands for many other companies. I have heard some say that the main difference is quality of components. For Example I have heard claims that HW makes Orion ESC's as well, but Orion will include higher quality parts... in contrast I have heard that HW makes the X-Car brand but with very low quality parts. I believe Brushless Hobbies (BHR) was the company who spec'd the X-Car version, unfortunately the owner passed away and the company went out of business:

HobbyKing continues to sell the X-Car (BHR) ESC.
