Had a 4S Otter Box. felt the case was a little too heavy. However I live on a farm and ruggedness of protection is very important. However with the 5S Otter Box I have the same ruggedness, great protection os phone and the case and phone feel lighter. It also looks at this time that the 5S case is tighter not letting dust collect between the face of phone and the Otter box face cover. Very pleased at this time. Have had Otter box 5 weeks. It is harvest time so my phone is in a very dusty environment now.
