The only cases that I dislike outright are the Viva Eco-Boxes. I like Viva Elites, but there are a lot of breakage issues. The only problem that I've ever had with a Vortex case was actually with a multi-disc version, where all of the discs on swing trays were fine, but the last disc had a defective tab on the disc tray button, so the disc wasn't really held securely in place.
Photo Clarification
To clarify the original post, there isn't a photo of the 12.5mm "six-ribbed" generic double-disc case because I don't have any samples of them. I have photos of the six-ribbed and four-ribbed 12.5mm single-disc generics, so, did I buy those in an attempt to buy replacement Viva Elites? Ahem, let's just say that those generic cases seem to be popular for...Adult releases...which is kind of ironic in that these generics lack a certain firmness (snicker) in comparison with Elites, due to a lack of the additional two support walls on the disc tray-side of the case.
Warning about Retailers Who Stock 12.5mm Singles and Doubles
When attempting to buy replacements, especially for Viva Elites, please be aware that retailers may be highly inaccurate with their sales presentations. For example,
Mega Disc Store (
http://www.megadiscstore.com/index.p...d0f0d1a485fa7a) puts "VIVA Brand" in its item descriptions, but as with so many other retailers, has a photo of the six-ribbed 12.5mm single-disc generic case, and an image of the four-ribbed 12.5mm double-disc generic. Let me repeat that: Most retailers selling both 12.5mm single- and double-disc cases are actually stocking generic six-ribbed singles and four-ribbed doubles.
For the longest while, I thought that
US Digital Media (
http://www.cdrom2go.com/catalog/blu-...d-cases_73.htm) manufactured generic 12.5mm cases, but when you look at their photos, again, it's the six-ribbed single and the four-ribbed double. At least with Octave, although the accompanying photos can't really be enlarged all that much, the single- and double-disc cases appear to be the six-ribbed design. Likewise, with Polyline, the singles and doubles both seem to share the four-ribbed design.
