Not convinced - SightMark Wraith HD 2-16x28mm Digital Night Vision Rifle Scope, 50mm Tube, Second Focal Plane (SFP)

So I was hopeful this would be a great buy. However, not sure that it was. When zooming in,the picture becomes so pixilated, that effectively the objects become very unclear. Also, I bought the battery pack from sightmark. When I used it the first time, something going wrong when using the pack and the scope. The image completely froze up and I had to remove the pack and the batteries to be able to reset the scope. When I went home, everything started working again. So it may have been the cold ( around freezing)
