Just received a used one off ebay today. It has major focus problems due to the front focus not being able to focus enough. If I could turn the focus ring more, I am sure it will all come into focus.
Here is a tree about 20 yards away, from my phone, through the scope and then through the scope with the pinhole. The pinhole sure does make a difference. Yes I am looking through my sliding glass door. It was the same whether I opened it or not. I found out about that pinhole trick from the link below. I hope this helps someone as I was flabbergasted.
