I had the regular ballistic case as well but I sold it because I wanted a holster case. I sold it to a friend who still uses it and has no issues. I actually have two otterbox defender cases for my old note 2 and no stretching what so ever. Still a pain in the but to take on and off. This is the first maxx design to be offered, my wife has one on her S3 and if you use it with the screen protector as it's supposed to be, It will keep its shape. Sorry you had such bad luck.
