Anyone with an Evolution II has any trouble with battery doors staying closed, 'cause the tabs have broken or bent? How many times can you take an Egg apart before the plastic screw wells start to break. Anyone dropped one on a concrete surface? How about 5the tray/ neck breaking? The lid splitting? Switch getting shot?
I agree that the electronics in the Evolution are more robust than the older Halos, and they can read any color shell. They work in a simpler way, and are poor fool proof. To say they are more reliable ignores the ways they do break, which is to say catastrophically. The board may not have issues, but the plastic bits do.
Halos aren't perfect either, and both have their relative merits, but they can both break when you play hard, and Halos feed faster. That is what decides me.
