Such an assessment should assume what you would expect. I expected at this price / performance ratio battery that does not have the capacity of the originals, but are cheaper by far and also work. And they do. Loaded and into the battery compartment of my 70D: smooth, without wobbling, as the original. The camera recognized her immediately, charging capacity display and trigger counting function. So both batteries were first individually and then together in my new battery grip. Again, the 70D immediately recognized each the two batteries and shows me now for each separately the capacity and trigger count on. The test photos with two batteries in the battery grip no drop in capacity, even when using the built-in flash and Live View mode. Video function I have not yet tested. If the battery there or even show other shortcomings, there's NEN Addendum.
