Approximately an hour using the wrong tools the first time. After I had the right tools it only took about 30-40 minutes total taking time. I recommend this video for disassembly. https://www.youtube.com/watch?v=6aQn-Hkv...

Buy 3 exacto knives (about $3-5 each). I recommend this, but make sure to wear a good glove with grip on opposite hand. You might dull down the blade by lightly scraping on rough surface (concrete), but this can break the blade, so I used extra care & used them sharp. If you have a Gen 6 ipod the seal ‘is’ really tight, so I took a pocket knife & ran it along the right side to free up any glue & get the opening started. Again be very careful of slipping off. Then follow the video. I bought one blue “ifixit opening tool” that came in handy after I got the front to lift away from the back & slid it along the side. Good because it doesn’t go in deep to damage anything. Tweezers to dislodge the battery cable & a needle nose pliers to bend the clips down when closing. (and 1 band-aid).
