Overall this is a pretty good product. There are some rough spots that could use attention such as the More Skill Points Setting Rule having the wrong text and the Lanuages Setting Rule being very unclear. It seems the intent was to just treat languages other than the character's native tongue as skills.
The only real drawback that I noticed was the lack of creatures. None of the creatures from the Polaris system have been converted. Converting at least a few of the monsters would help establish a baseline for GMs who are unfamiliar with the original Polaris system.
As it stands now, even with the SWADE conversion document, There's still a fair bit of work that would need to be done by a GM to do the setting justice.
Personally, I would be happy to pay for a full Polaris SWADE setting book.
