I've had issues with the lift mechanism loosening and falling out of the case. Maybe I've just been unlucky. I don't see why there would be stress exerted on discs unless the center post is too tight. Some other reason I don't know about?
Source for high quality jewel cases

$16.00 for 10 count, plus shipping and, depending upon your location, tax.
You're welcome ! ;o)
