grey item, probably the best cover you can buy for this phone as it gives you the best (lowest) overall thickness as most s4 users know the back of the phone is the cover.
this is a geniune samsung product, but made for the chinese market. but once its on your phone you wouldn't be able to tell the difference, totally identical to my friends official uk version (£30).
comes from hong kong, and gave me about a 3-4 week delivery time, but it actually came in less than 2 weeks.
can't fault it for the price and there is a seriuos difference in built quality between the official covers and the cheap chinese ones that has flooded the internet. If you dont like the look of lack of protection from the official samsung case checkout other reputable brands such as spigen who make tougher cases for this phone.
Personally not too keen in the s-viewer as it defeats the purpose of protecting the screen.
