I got mine from San Fransisco a few years ago. It was shipped up to me ( I live in Alberta, Canada) by UPS. The seller packed it extremely well, but I was very nervous non the less.
The liquid was a mess. I tried filtering it a few times, but it was hopeless. I decided to give it a wholesale liquid change. Distilled water, a few drops of dishsoap, some sea salt ,and a few drops of blue food coloring. The wax is original.
It takes a couple of hours to get up to speed, but then it can pretty much run all day.
The cap does not have a hole in it. I believe that rumour started a few years ago. The spun aluminum on the cap comes to a sharp point, and the aluminum at the point is a bit weak. It's likely that there was an Imperial out there that had an unwanted hole in the cap.
