I also just received the same case. The outside front lower right is stamped 'Carry Mobile'. The N810 fits well in it, and the plastic does not seem to snag the slider either going up or down. It's a good question as to if memory cards in the two slots in the inside upper portion of the case will over time scratch the screen. I'd say miniSD cards will not, particularly if you put them in sideways although this will make getting them out more difficult. A SD to miniSD adapter, being larger, has more of its surface exposed and might be more likely to scratch. This would, I suspect, depend in part on where/how you store the case. Somewhere where the cover was constantly bumped would increase the odds.
