Pros
None. Never got it to work.
Cons
I don't think they have properly integrated this with Lion. There are a number of youtube videos on the topic. I also tried a later incarnation, but never got the blocked list to populate. Went back to using a block list in Vuze.
Summary
Will be interested in trying again when bugs ironed out.
Installs easily and works well in the background.

Summary
This review was originally posted on VersionTracker.com.<br /> Installed on current "tiger" OS. Started per instructions. Checked the log to display blocked urls only. Started my P2P and did a few random searches. There were lots of blocks -- and a whole lot less garbage results in the P2P searches. I'd give it 4 stars for the garbage filtering alone! BUT (the deal breaker for me) is that I use dot mac as my mail service. PG's documentation about it starts a chain (answering the Q of why refers you to another section that sez do xxx--- that results in a "can't do--- do yyy instead-). End result, I could not get my mail. I removed everything manually and rebooted to get my mail back. There is NOT a clean simple non-geek uninstaller included--- and the naming of the components is not consistant enough to rely on Spotlight to find them all with a single search.
how to remove.

...Ban List.<br />This review was originally posted on VersionTracker.com.<br />Installer hangs, force quit, reinstall then it works... Were the Contextual Menus to Start, Stop & Upload Ban list ever made available? Would love to have a copy! No Access to Apple.com or Apple's iTunes Store come on... There should be a way to make an exception/s to the Ban List or at least a way to turn it on or off. Zipcod1@aol.com
A bit crap really.

Summary
This review was originally posted on VersionTracker.com.<br />The installer constantly crashes, the commands to delete the program don't work. Locks out some pretty odd sites, apple.com being the noticeable one and the author doesn't seem to want to support the product or bug test it correctly. He only seems to appear when people give him accolades. Might be a good program in a years time. I'll stress again it needs to be bug tested properly.
Good work

Summary
This review was originally posted on VersionTracker.com.<br />I think this is really good software. I especially like, that it won't flush ipfw. Because I have setup throttled too. What I would like to see is some kind of log, so that I can see what happens, if update is successful. That would be nice.
