content: This product works well, with no problems so far. I have now had it for about a month, and it keeps my iBook G4 running with no issues. It doesn't have the light that indicates whether power is being received, but that's a minor thing. Also doesn't have the easy-to-use cable-wrapping things on the original, but once again, that's a mere quibble. All in all, I am satisfied with this purchase.
