[Q]: Review: I bought this because it was a cheaper alternative to Mac's (ridiculously priced)$80 charger. At first it worked pretty good, but about a week or two after i got it it seems to not be working like it should. i think there is some kind of warranty, so i should try and exchange it...but sometimes when it is plugged into my computer it will charge for one second, then stop for one second, charge for one second, stop for one second, etc. It still manages to charge the computer, but im not sure if all this on\off stuff is necessarily good for my computer...

[Q]: Review: Watch out for this turkey! Definitely a disk for the true believers only. Sound quality as bad as any bootleg I have ever listened to, some songs fade (on a live album!?) and skimpy liner notes add up to a pretty bad package. And the addition of a keyboard player seems to hurt rather than add to WA's sound. If you are dying for a live disk from WA's "Locked In" tour, this will have to do. Otherwise, save your money.
