I also am well-pleased with the Gecko Slimfit for Aura6". The blue one is such a beautiful colour. Very good quality, but definitely not cheap compared to those on Amazon/ebay sold under various names.
I have one of these cheaper ones (in purple) for my AuraHD. It's held up well despite its cheapness. I do handle all my gadgets like precious jewels, though. My husband thinks I'm a bit obsessive about it
