My Trifecta is one of my favorites too, no problems with it yet. It always lights, never goes out even in the strongest winds (waiting for a hurricane to put that to the test, cause I'm gonna light up as the winds start to blow!), and looks great to boot. And like you said, I kept my instructions and I'm caring for it as instructed.

Granted, it's one of the most expensive Colibris I have bought. Some of the cheaper ones I have had some problems with.
