I ordered 2 of these, 2 weeks apart.
The first one came in a shiny box, it has full 640x480 resolution and 15 frames per second, fair picture quality.
The sound quality was really horrible, you might be able to hear what someone says if he really articulates the words and stands within a meter in a silent room. Sound is 16bit 8kHz PCM (wav).
The second one came in a box with the same "MP9" design, but not shiny (not plastic covered cardboard), the resolution was 352x288, 16 f-p-s and bleached colours.
Compared to the other pen the sound is fantastic, even though it's also 16bit and 8kHz.
So, you are joining a lottery here, either you get fair picture and crap sound, or fair sound and mediocre picture.
And apparently i can't write f-p-s without the dashes since it contains the characters f and p after each other...
