The cover fits well to my S4 and has one year and not discolored (as opposed to an earlier clear envelope from my S2). It also dampens the fall energy sufficient so that my phone has a few crashes unscathed from his hand. Small Gimmik on the edge: I use daily a removable battery and peel off this sheath takes the S4-back with the same (remains in the shell) and assembles them at reassemble smoothly. :)
