The case provides protection in the pocket, the N97 can be but ill trigger the envelope and occasionally captures gewurstel on, namely when you want to have the particle quickly from the case - for example, at a discuss if you have forgotten to "silently" to make! You need 2 hands, then it is not optimal!
The biggest bug, however, the lack of opening for the headphone jack. Who the N97 as a radio or MP3 player uses - the can operate only outside of the envelope! I would have expected a little more thought in the design of this windy particles.
Summary: I habs bought, it'll use and exchange at the earliest opportunity.
