I pre-ordered the alternative battery grip from ebay that was posted in the forums some weeks ago. It just arrived. I don't own the real canon BG-11 so I can't compare those two.
At first glance, it feels plasticky but solid. Definitely not as solid as the 5D mk III. I own a genuine Canon BG-E2N, the grip for my 50D, and I can say they feel very similar in terms of build and rubber grip but not the buttons/dial. The buttons are very tactile, they actually click unlike the buttons on the 5D mk III, some might see that as a postive or negative. The dial and joystick on the grip feels more relaxed/not as tactile compared to the ones on the body which gives it the impression that they're more sensitive/weaker. Surprisingly, the shutter button feels almost similar the the shutter button on the body. The battery cover from the body attaches by its hinges and locks on the part that goes in the body.
Overall, its worth the $90 I paid for it.
