Mark,

I love them. I live in Myrtle Beach SC where corrosion in outside
metal parts is a major problem. On the oceanfornt, metal disconnect
boxes rot out in a few years. The plastic ones last almost forever.
It just depends on your situation. They are great for corrosive
environments. The fill a need, and that is what it's all about. Just
use them where you need corrosion resistance, use the metal ones
everwhere else. That's what I do.
