My husband and I purchased a mid-century modern that had been "colonialized" for 17 years.  These fixtures brought the interior of our home right back to the period and everyone who visits LOVES them (so do we).  We are actually ordering 6 more for the basement!!!

Pros: I love the versatility and ease of installation.  I can install one of these in about 15 minutes and I usually avoid plumbing and electrical.  I also love that we can use these at at many different heights and flush mount!
Cons: N/A
