This is a solid replacement for Apple's charger. It is light weight and does the job it was intended to do. Blue "on" light simply tells you it's plugged in, but there's no indicator to tell you when the computer is fully charged. Lacks the portability elegance of the Apple charger, but costs a lot less.
Positive
