Hmmm again a review REALLY is difficult. The calculated what Canon for its Battery Grips I find quite outrageous, comes to me only a battery grip of a third party in question. Decisive for the purchase of the Polaroid remote release was contained. And that is also the biggest criticism. The connection to the battery grip is working sluggishly and the remote control also has only an extremely cheap-looking button which has no clear pressure point. That the grip is not so wertig how the Canon grip, I knew and that I can also live well. With the look and feel I am very satisfied. And the recessed thumb rest I find very enjoyable and stands out from Canon even a bit out. Also the pressure point of the trigger I quite like (actually even better than the on the 7D). But the remote release is not to be used, you never know if the camera has been triggered, or not, as long as you do not sit in front of it and the mirror really listening. Also it has to focus not have its own button, not like normal remote controls a switch with two pressure points: press for light focusing, Pressing for triggering. Another criticism is that the clock is adjusted continuously. Why this is I do not know. In addition, the included manual is unfortunately just a bad joke. You have to guess rather how to use the handle. As similar attacks by other manufacturers to look exactly the same, however, I go times assume that this is an OEM product, which is sold only under various brands. So I'm going to keep under control.
Again summarize:
Positives: - Very billg (relative to the Canon original) - Works well as a pure battery grip - Good pressure point when trigger - Very good grip
Negatives: - Remote Trigger practically useless (can not focus, partially dissolves from not at all) - Extremely poor guidance - Clock dissembleth - Material of low quality - Cryptic non-intuitive.
Hmmmm two stars are actually too little, but too much three. The essential function is given, but since the remote release for me but was a main selling point, but I'll probably round.
