Mine had a little extra glue around one of the strap attachment holes, but whatever, it’ll wear off as I use it I’m sure.
I am an absolute freak when it comes to the device itself; I will return it over the slightest defect and buy a new one until I’m happy with it. But in my mind, the case exists to take damage. I don’t care if the case is imperfect because it’s going to get dinged and dirty and some extra glue peeking out of some seams just makes me think “wow this thing’s really glued in there well.”
