Imax b6ac Geniune???

I bought a long time ago one imax B6AC in HobbyKing. I recently saw some videos that show that the model I purchased is not genuine, to my surprise. Always trusted in HobbyKing, and actually seeing the announcement of the product (http://hobbyking.com/hobbyking/store/6478IMAX_B6_AC_Charger_Discharger_1_6_Cells_GENUINE_.html) the product leaves a doubt in the air.

The video I refer to is this: https://www.youtube.com/watch?v=JacYAHJcjzo

I want an explanation of HobbyKing, for I am buyer of at least 2 years, and I think I deserve such an explanation. Even says in the announcement that the product is original and that if I wanted a cheaper product that then yes I bought the fake.

I wait for the soon return of you.

Flavio.
