My star rating is really 3.5! Its probably better than OK, but not quite as good as I expected. Great looking signal that works very well once its connected. My only disappointment was that it does not clip into Peco streamline track, as the contacts on the prongs don't come into contact with the underside of the rail...which wasn't really evident from the description. That said,after a bit of wiring and soldering the signal works really well. If you do end up wiring it,then just ensure its well connected, its very sensitive to failure if the wires aren't well soldered!
