This case is made of such a higher grade that the regular seidio rugged for the Evo,,,the silicone is extremely snug..and the lips of the silicone corners don't easily move as with the regular rugged case,,,the skeleton is also made much thicker and once on almost impossible to take off unlike the reg rugged skeleton which would sometimes disengage from the case when holstering,,,,I own the defender along with the ballistic,,, and this case is beyond the defenders level,,,and seems to be on the same level as the ballistic as far as overall ruggedness,,,
