update
thought i would post this info, or update however you want to look at it. had the case on the fone for 13 work days. very dirty environment. pulverized coal, cinders, ash, dust, heat, grime, to the max degree. took it off today as i am going into my monthly off time and thought i would disassemble and clean things up. also i was curious if anything was getting inside.
on the outside the case looks as shipped. no signs of any wear at all other than some extremely minor scratches on the case screen. but you have to hold it just right in the light to see these hairlines. smaller than hair probably.
i have not dropped the fone. most likely do to the case though
upon opening the case up i found the fone to be completely spotless. it looked the same as when installed. some lint was in the case but no dust or dirt or anything abrasive. the case did not mark the fone at all. nada.
there was some dust between the rubber cover and the hard case for sure.
i rinsed the rubber part in under water and its perfect again.
for me i dont think there is any further need to remove the fone from the hard shell for cleaning but maybe 2 times per year. the rubber i will have to remove every two weeks i think.
that said i have to also say i really appreciate the screen again with nothing over it. i.e. anti-glare and otterbox. no grain, much brighter, lovely.
and the audio is much better from the speaker.
so i am gonna run naked <?> for a few days to bask in the iphone-ness that it is. but there is no denying that my fone would look nothing as it does today were it not for the otterbox. save for the screen. i dont think the screen would have taken any wear had it been naked. but the gloss black back would be scratched. and my jacks would probably be fouled a bit.
i have issues with the case no doubt, albeit minor, but there is no way i feel there is a better case for my needs. this case is absolutely worth the money and minor troubles to me especially looking long term.
hope others find similar results to mine.
