At this point, I don't see any advantage to the 5x or 6x price premium for "Genuine Nikon" if they are just going to break.
Breaking once? Things happen. Breaking twice in the exact same manner? That's a design flaw. A bit of Google searching last night tells me this is a common problem with these.
Funny part is I went round and round when I first got it, wondering if it was a knock-off or not (there is a pretty long thread here somewhere dealing with that). In the end, my conclusion was that if I had to try that hard to tell the difference between "genuine" and "knock-off", then it didn't really matter anyway (other than potentially way over-paying).
My ultimate confirmation came from sending it in for repair to Nikon. If its a knock-off, it fooled even them, and even accepted Nikon replacement parts? I doubt that. Its real Nikon.
And its a POS.
I haven't heard back from Nikon yet. If they refuse to fix this under warranty, I'l probably just buy a knock-off and toss this one in the bin.
