No NX-Alpha for me today...got home, took a quick look at it, and there's no wonder it had trouble breaching the warp 2 barrier - the rounded connecting piece between the two rear stabilising fins was missing. It wasn't even loose in the box - that would've been different, at least I would've been able to glue it on - it was nowhere to be seen. Had to return it, and as they didn't have any other spare copies, they've ordered two more just to be safe
Here's to hoping that the next ones are correct...
And it isn't like it's an issue affecting all of the models, either - I've seen reviews online where the part missing from mine is there, and in one where the person had to glue it on because it was loose (I couldn't even do that...

).
