Do what it will, however, bulkier than other brands

I had in front of 6D a Fuji X-T1 and a Nikon D7000, and sooner or later had to both the battery grip. So even with the 6D now, because in the vertical position, a second trigger is much more pleasant than to bend the hand, and the ability to run 2 batteries at the same time, of course, is great (I need the camera again for filming and she eats very quickly by the batteries).

Compared to the handles of Nikon and Fuji this is clearly massive, but is still well in hand (larger it should be but really never, otherwise you'd need huge paws to hold the handle can). Processing at the same level as the camera, the buttons feel also like the body and in addition there a sled for 6 AA batteries (which I will personally while using only as a backup, but if you take really stands out in the sticks and the camera is empty, you get faster in doubt batteries as a new battery). Therefore 5 stars because the handle does exactly what it should.
