I just received my X5T-HA today as well. What a great little light. It looks so sleek and understated. It came in the plastic Inova case, but mine did not include a sheath. I don't mind, though.
My girlfriend and I played with the X5T-HA and the X1 all night. At one point she threatened to drop my X5T out the car window, and at first I dared her to do it, but then I remembered the non-shock-proofed LEDs and thought better of it.
One thing, though. The new X5T has made me appreciate the little X1 all the more. I haven't used a better light for up-close work.
