Very happy with this lens. It seems very well put together and feels solid in the hand. It renders sharp images even wide open with very little chromatic aberration. VR II funkerer excellent, I've got sharp images handheld down to 1/5 seconds shutter speed. The only thing that pulls down is that there is a fair amount of barrel distortion at wide angle and pincussion distortion at telephoto end. This can be corrected very easily in the camera when you shoot JPEG or post production.
