[EX Q]: Had to return it several times for a close enough fit. A size XXX is actually a large adult size and medium fit around the arm/shoulder area. Finally gave up and got a full refund.
[EX A]: negative

[EX Q]: Just opened my plastic package because hard to see if center pin was copper as pictured in ad.. sadly it was not. By the way, do not tear open your package because it states on the package,"No returns if bag is open" what a waste, I should have just driven to an autoparts store.
[EX A]: negative

[EX Q]: I was going to buy the name brand case but decided due to price to try this one. It's much better than the name brand for less money and has more features.
[EX A]:
positive
