I quite like the elite 4-6 way Blu ray cases (But I re-house alot of my disc's, say 2 parts of 2 disc get re-housed in an elite 4 way case).
But yes that 4 prong set up does lead to the breaking occasionally and I have only come across the very odd one that doesn't really hold the disc/ defective (basically I think it due to them not giving enough thickness for the disc)
But certainly won't disagree that they are not as durable as a lot of the other disc cases.
There is a variant from the elite cases that has a thin ring of 3 prongs and a center circle, which I thought they might be trying to bring in as an alternative to the 4 prong version, but they've been around for a while and I don't seem to see to many of them. So maybe one day.
