I had a difficult time holding onto the Samsung S4 and was looking for something to give me a bit of grip when holding the phone. I was looking for a TPU case since there's less stretch especially around the thin parts of the case and this one looked like a good match. Fit is dead on with cutouts lined up perfectly. The power and volume buttons are covered by the case but the case is raised where they are and pressing them, though not as easy as without a case, is not an issue.
