PS: the seller is 247Media
PS2: The seller assured me by email only sell original products, it may be good time not knowing him even detect a counterfeit.
So I made a final check: The battery in the remote control is not one advocated Canon, namely a CR2032 while this remote is equipped with a CR2025.
So to sum up: Cover coarsely imitated, strap hole smaller than the Canon original, battery that is not the original one, I would add that the Canon has a protective film over its surface that may have then remove that here no film covers the remote control.
The seller and Amazon have can not be aware of these facts but this product is indeed a counterfeit.
PS3 Amazon now sells the product directly and we can therefore expect an original, thank you for reactivity and removing the item to the seller.
