Even as lousy as these pics are, you can still see how much of an improvement putting wiremold in makes.
I have all concrete walls and ceiling. It's an old apt bldg, so I had no other option.
These are kinda like before and after shots
Ignore the circled speakers, but do notice the wires running between them, and also note the wire running
out to the 3D glasses emitter
Here, all wires , um , molded LOL
You need to look close, but you can see the wires running above the screen.
Again, wires - molded - MUCH better.
I have a few cases of this wiremold left over, let me know if you want some.
