Mine also arrived much earlier than expected and while it has a strong chemical smell right out of the box, the leather is softer than I was expecting.
I do have the issue where if I force it wide open and squeeze the lid against the back it will lock. But if I fold it over and let I it sit naturally it does not happen.
Another bonus is that the case and iPad fit into the STM sleeve that I bought with ease. I wanted additional padding when I put it in my backpack and the STM provides that.
I think I'm going to take some leather cleaner to it to hopefully reduce the odor and maybe even apply a light coat of conditioner on the exterior to also mask the smell.
For $40 delivered I'm pleased.
I wouldn't do that for a few days, the odor will will go away after a few days. You will just seal the glue smell in. Put a dryer sheet in the case and put it back in the bag over night
