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: Buying a Sony cable wasn't worth it. I could have spent less buying any 4pin to 4pin 1394 firewire cable. Search around. Buying name brand may not be worth it.
