[EX Q]: You aren't saving any being this adapter. I purchased this for a 12" G4 Powerbook. The power it supplies goes on and off constantly. This can't be good for the computer. It certainly doesn't charge it. Don't waste your money on this Macally adapter. Try to find an original Apple adapter if you can.
[EX A]: Negative

[EX Q]: I ordered this DashMat for a specific vehicle, it was not the correct mat. I returned the original one and they sent me an exact duplicate of the wrong mat. I can't seem to get the correct one and therefore it sits in a box!!!!!!
[EX A]: Negative

[EX Q]: The designers threw in the works and the lone star represents a point for design ingenuity. Problem is this toy is nearly impossible to build and it's more than the comically unreadable directions that are at fault. I have built many a toy but never found one this resistant to having its snap on parts snap on and of course if and when they finally do, the least shake will undo your labor. Sure to end in tears and frustration for all.
[EX A]:
Negative
