Anyway: this handle fits right on the 70D feels good and in my view there is no difference for optical camera (yes is often criticized for 3rd party handles). The shutter release button feels slightly different than the act detrimental to the camera, but no. The same applies to the other buttons and the scroll wheel. I notice when taking pictures no difference.
What bothers me is just something the locking wheel, with which the handle is screwed into the tripod socket of the camera. Is it tightened, the wheel seems a bit lax, as if it is braked in the inner of rubber or foam. However, in practice, hardly bothers, because the handle is tight and does not wobble, etc. Therefore, no deduction.
Overall, a good buy, not just because I've saved a lot of money (75 versus 200) but to get a proper battery grip have that as well feels like the original BG to my 350D.
