Samsung Flip Cover for SAMSUNG Galaxy S4  (Pink)

Makes your 40K phone look like a 20k phone. The quality is good but the back panel is dull matte finished. Not worth the price. The inner cover catches dirt quickly and in a matter of days it start to look old.
Good thing is that it is washable and after multiple washes the front inner and outer surface does not wear out.

Works well as a flip cover, but protects the screen and not the entire phone. Since it replaces the back cover of the phone, your phone isn't afforded any extra protection from falls and bumps.
The issue with the pink colour is also that inside portion is made of felt cloth (the part touching the screen) and starts to get incredibly dirty within a week. So your phone is bright pink, flip inside and it's a dirty brown.
I'd say go with a black to be safe. Also, it is pricey for it's features.
