A few months ago I bought a \"genuine\" Canon grip for my 5D MKII and it also came with 2 \"genuine\" Canon batteries. All this for $250. It smelled fishy then and I should of walked away...but I didn\'t.
Got the grip and the batteries and all looked legit. Only problem was the box was crushed in one corner and subsequently one of the brass pins on the grip was damaged. So I sent it back only to find the seller is not even on Ebay anymore even though I was in contact with him about the damage grip. Thank god I put insurance on the package.
As for the batteries. The two I have have no code imprinted on the body where my two legit batteries have. The serial numbers are different but only contain 7 digits and not the 8.
