I actually bought one via Amazon cause I was afraid it would be slippery using it especially since it is thin. Nope, this device just feels awesome for me personally holding and using it. It is just a little taller than the Moto X which I feel is the best ergonomic smartphone I ever used. And the 6 is basically the same size albeit thinner than the HTC One M7. To get a feel for my hand size, I can palm a slightly deflated basketball or one with great threads fully inflated. I'll probably hold unto the case and when I'm not using the 6 I will just put it in a sleeve I have for protection.
