I have average sized hands but I find the X-T10 and X-E2 I can potentially drop the camera. I typically shoot with no neck straps since I use a spider holster.
Picked up a Neewer L plate bracket hand grip and it's a substantial improvement.
GT5000 tape with this bolt on grip makes the camera more ergonomically pleasing have a grippy edge to hang onto.
With the grip tape the feel of the body appears to be as if it's an OE grip.
Hope this helps anyone considering such an inexpensive item that can be quite beneficial.
