I'm interested in where, and if the problems are limited to the ones offered here or include the KickStarter cases (assuming these are not the KS cases.)
The plastic often has all sorts of cosmetic flaws in it, especially noticeable in the "SX-64" color scheme case and the breadbin color scheme. These same flaws were present in the kickstarter cases, and is due to the molds they are being pressed from having flaws in them due to age and use. The dies were in reportedly even worse shape after the kickstarter run, prior to Jens buying them. Supposedly, "a lot of work was done to refurbish the molds" such as polishing, etc. However, this does not show in the finished product, as there are still glaring cosmetic flaws present. The kickstarter case that Dallas produced here in the USA sold for $20. These guys are selling their product for 100 Euros (some of the color schemes were less expensive, such as the white/beige case), no doubt taking the lead from the new A1200 case price, which were at least made from new molds, so, may justify a higher price.
I had ordered one of the new 64 cases, but, as soon as pictures started showing up on the C64 facebook group, I promptly cancelled the order and bought one of the remaining kickstarter cases on Ebay for $22.
