I haven't honestly messed with it very much, but the basics work like this. You save your preset stations, then it will record up to 8 hours per station all on it's own. It will then record over what you have buffered with newer content. I usually listen to music replays, so it's tougher to know exactly when it was recorded. Since I haven't used it very much yet, I'm not sure how often it does that overwriting thing. What you can do when you're listening to the playback is is hit the fast forward or rewind button to skip to the next segment. (No scrubbing) So when the carbonite commercial comes on, click, ashley madison, click, hotel, click, back to the show. It's not a bad way to listen. If a guest is on that you aren't interested in, you can click past them, or back up (to the start of that segment) if you want to hear it again. I've got 7 hours and 43 minutes of Howard 100 and a total of more than 100 hours of stored content (combined) from all 15 presets. You should never be without something to listen to.
