Misrepresented!This is not really an "extension" cable so much as a longer version of 8886. The bottom of one plug has the old 9V plug on it, so it severely limits it's uses in many cases. I would not have bought this if I had known that. If you knew that beforehand, this is a fine product and serves it's purpose.
Now LEGO needs to release a proper extension cable with no 9V stuff involved.

Good extensionThis is a good long extension wire for getting power to things far away, and it is compatible with the old motors and things, but it is a bit expensive for 2 conductive bricks and wire.

Very Few LimitsAfter a few weeks of tinkering, this product is definitely earning it's keep. Most of my projects actually utilize both PF and 9V components, but even a strictly PF setup runs smoothly. It gets a bit clunky if you're running multiple wires in a narrow corridor (such as the 60051 High Speed Train) but it still conducts power without fail. I hardly see any reason to give this widely used product a low or average grade.

Compatible with "old" 9v systemThe only exciting thing about this wire is that it will make the Power Functions motors, lights, etc., compatible with the "old" 9v system. For example, it will connect to the 9v trains transformer.
