Too bad so much junk is out there. I dread most models of Hunter ceiling fans. Brackets with rubber feet are hard to mount, specially on damaged ceiling. Rubber feet also keep falling out when handled. The fans don't hang square to ceiling, the blades often need balancing.
I despise hockey pucks.
Wiremold is OK for straight runs. A real pain with lots of 90's, can't be neatly bent for offsets, etc.
Chandeliers aren't too bad, but I hate ceiling medallions. Flat plastic ones aren't too bad, but I truly hate the thick foam type, especially oval ones. Nothing but trouble. I hate chandeliers in high foyers and no space to spread a ladder.
