I have another grip and it is far better quality than this grip. The issue with both of them is the base of the grip is not exactly to the OEM specs and they both are slightly wider and won't let the battery pack come out through a Really Right Stuff L bracket - though the OEM grip has no issue. If you just want the grip and never use a battery grip L bracket, I'd pass this one and get another.
