Sightmark xk-nvn-sm18013-demo - Sightmark Twilight 5x50 Digital Night Vision Monocular

I have had one of these digital night vision for 10 years with no problems. I wanted another and when I received it the rubber coating on it was deteriorating and was very sticky, also a plastic piece on the front was broken. Electronics worked fine. I know this was a reconditioned unit but I think they could have done better than this. The unit was non returnable now I know why. I would not recommend buying one of these demos.
