I have a colleague asked time to bring his original battery grip that we can compare times.
The original packaging looks a little nicer than that of Ideal Photo, but well packaged both been.
Visually no real difference between the original is to determine handle and the Ideal Photo grip. On the front is only the original handle the inscription Canon Battery Grip BG-E2N, with Ideal Photo handle is nothing.
Both handles feel the same weight and are equally well in hand. The grip of the Fournier is both handles equally well.
There is now nothing sticks and everything good and firm.
The only differences to the original grip that I could find were minimally different blue color on the buttons and the mouse wheel to hear something different about, not better just different.
My Conclusion:
It was the right decision to buy the Ideal Photo grip, and the 40, - EUR save. A strong buy recommendation from me.
