This adaptor and Apple's adaptor are not going to live long. They are all pretty worthless, except for the fact that you HAVE TO HAVE ONE.I just buy the cheapest 65 watt adaptors I can find (for both 15" iBook G4 and 17" PowerBook G4) and plan to replace them within 6 months. Every now and then I find them for $20 - 40.00, and buy 2 to 4 at a time. Next time I'll buy a new laptop with the magnetic plug! Am very disappointed in Apple. I love my Mac, but quality is definitely going down.
Negative
