This is a really nice and useful product. I use it with my 5th generation 60G iPod Video (even while encased in a silicon skin). I don't know why there are complaints about the sound of the hard drive spinning, but my iPod is always updated with the latest firmware so I never had any problems from the start. I always use the highest setting so the sound quality is awesome both for voice and music. The built-in mics are a compromise and we should not expect too much from it except for voice memos. For music, the best would be to get a direct feed from a mixer or instrument via the line-in or invest in the Audio Technica Stereo mic (and even then you have to be careful about WHERE you position this set-up). Also, make sure you have a power source attached for long recordings. Here's a tip; I use my PSP's mini USB cable (really short) with an iPod USB AC power adapter - it works! My gripes are mainly with the user interface which does not allow for any flexibility. But we can rename the files after the fact anyway. Overall, a really cool product and a must have for iPod users that need to have an audio recording capability.
