Nicely done. You know the quality of materials and workmanship that went into your extension. While you can purchase a cheap extension strip from an online retailer for a lot less you can't trust the build quality on most.

I had an issue with a supposed 'quality' surge suppressor years back where one of the outlets was intermittent. First thing I did was replace it, afterwards I tore it apart and checked it out. Instead of solid connections between the copper wires and the metal blades in the outlets they were just pressed together, slots in the metal blades clipped onto bare copper wires. I ended up soldering all of the connections in the strip but I was appalled of the build quality of a $70 name brand surge suppressor.
