Today my Ultra2 case brittled even more when I had it to open (and not 
at the glue point!). I had glued this one with Cyanacrilate.

The metal sheet now comes off since plastic rivets brittled too.

The case is marked PC-ABS

so Polycarbonate + Acrylonitrate Butadiene Styrene

ABS is a very high quality plastic and I have objects last long... so 
there must be a production issue for it to age this bad.
