I was a bit hesitant after reading a few negative reviews, but the unit I received works perfectly. I checked for the issues others mentioned—Pines in wrong order, and bare connections—and mine had none of those problems. Build quality seems solid, and it's doing exactly what it’s supposed to. Glad I took the chance on this one.
