The large windows on the front are perfect for seeing who is calling as well as for turning off the alarm function. It stays clean (I have this case in white) and after a few weeks of normal use there is no wear and tear like my last case. The rubbery ring holds it snugly in place.
The only down side is it can be challenging to get my charger to stay connected -- need to unsnap the case when plugging it in for a recharge, but many cases are similar.
My previous case used a magnetic clasp and that magnetic field interfered with the stylus use. This case doesn't have any issues with that because the "lid" just falls down into the rubbery rim around it.
