[Q]: As a student of jiujitsu i understood alot of the moves but i found that without previous knowledge these pictures and instructions were difficult to understand. I feel there is alot of good information but not worth buying.
[A]: Negative

[Q]: I've now been through three of these cords. they seem to last around a year before just dying. The first two eventually had fatal connection issues with the piece that connects to the computer, however my third one has just died and is actually not getting any power from the wall. The little indicator just fades out, and now won't come on at all. Yes it's a lot cheaper than the other cords, but I'm just not sure its better. I know lots of people have problems with the apple cords as well.
[A]: Negative

[Q]: A catalyst in the Contemporary Era revenge-actioner movement, this George Miller flick features a young, then-unknown Mel Gibson in only his second movie role, as top-cop Max Rockatansky. After a pursuit of Max's ends in a fiery crash, killing the pursued (a biker named Nightrider), he is targeted by motor-terrorists for the death of their fellow gang member. When Max goes on a vacation trip with his wife and their infant son, they are attacked by the malicious, vengeful mob, leaving Max a childless widower hungry for his own violent revenge--and that's exactly what he gets. Set in post-apocalyptic Australia, this film, made for a meager $400,000, held the highest cost-profit ratio of any film in Hollywood history until 1999, when Blair Witch surpassed its mark.

Positive
