After today arrived the battery grip with the Post, also a few days existing wrist strap could be mounted. After I read the reviews on Amazon, I was quite nervous before assembly ... but this turned out to be premature. Even without assembly instructions, it took less than 5 minutes to attach the strap. The adjustment of the length is no problem, with the perfect measure will probably turn out only during use. As always with Canon, the part is well finished. It is the back of the hand to soft and facilitates handling the camera much easier. One wonders how so far without coming out ...
