I wish a canner could do this... I would buy it in a heartbeat. The problem with the bottle filling, I was able to get 10ppb with my triple purge/vac, this one on a singe fill is 23ppb, and he said a double purge was 10ppb.. is that you still have cap ingress, which I have tested and is very real. I noticed a flavor degradation after 1 month even with a 10ppb fill (which very few can get). Now I would sacrifice 20ppb into a can since you will not have the cap ingress issue.
