The handle does what it should and works perfectly. Also it smelled when not unpack for chemistry. Unfortunately, even at delivery the stuck rubber was not bonded clean at one point (see image -> the image has been obvious from Amazon pity.!). The batteries loaded with original Canon charger without problems. Level indicator works without restriction. The batteries have been recognized by my 70D (under control and in the Cam) and associated (also the trigger counter per battery operated). The feel of the buttons is fine. Unfortunately the bar for me the camera is too clunky (perhaps only habituation thing -> love it or hate it).
What is not in the description: The battery compartment cover of the camera at the insertion part of the handle (like the original Canon-handle) are attached and will not be lost.
Due to the not 100% -optimal bonded rubber handle is (after 2 days and only recently try) back. Otherwise I would play around him because of the batteries and to further and perhaps keep to "get used to". To be fair, I must mention though, that I have given the seller of this no improvement opportunity.
