Protective Genuine Leather Case for Samsung i9000 - Black

Pros: It's cheap. Has an extra slot for cards.

Cons: Really smells horrible. Doesn't really fit well for the SGS. Need to push hard on the phone to slide it in.

Other: Buy this if you need your phone protected, and if you can stand the horrible smell of the product. It is cheap, so buy a few if you can. It will always come in handy.

Pros: Cut out for camera does not obscure lens
Comes with a credit card pocket
3.5mm audio jack is not covered (barely though)

Cons: Has a chemical / synthetic smell
Magnet does not easily clasp lid down; sometimes it pops open.
Leather strap across top covers the charging plug
Credit pocket is very slim / tight - can barely fit in a single credit card, no way you'd be able to fit two or more in there.

Other: Cheap and not a great build - I bought it because of the credit card pocket, but it's such a tight pocket that it's not very useful.
