Thrilled.  Absolutely thrilled.  We installed these in our bathroom and kitchen and are beyond impressed.  We love the simple look and the wide availability of bulbs (at least on Amazon).  Setup was simple, though the instructions were garbage and referred to a completely different product).  If you know your way around a basic lighting install, you're fine with this setup.

Would it be weird to install track lights in every room in the house?  Honest question.  I'm mighty tempted...
