these are an amazing product the only con is that under the layout it can be hard to tell North from south since both are black but this can be easily remedied by cutting one of them short and attaching it to a red wire. other than that these are great more discreet then terminal tracks.

This is what I was looking for! Hate to solder wires to tracks, this is fast and cheap way of completing this task

Fantastic. Just solder and off you go!! I do not see any con's. All pro's.
