Thanks for yours comments.
I recently bought two pieces on the top nearly $ 20. I think it's a fake though made very sharp, smart ... when put in the machine is still registered but currently only 7 number (the same number more on batteries).
The one at the bottom, it is the genuine goods because it's in my new EOS 70D.
But yesterday I've tried shooting it:
SEGD (fake!): 12 minutes, 14% of all batteries.
SJRD (fake!): 12 minutes, 4% of all batteries.
RH11 (genuine): 12 minutes. 12% of all batteries.
