• You ship to me your Apple iPod shuffle 2nd gen with weak or dead battery (please make sure that everything else works fine).
• Upon receiving your iPod shuffle, I can install a new battery within a couple of days, test it thoroughly and ship back to you.
• You won't probably notice any physical sign that your beloved iPod shuffle 2nd gen has been even opened.
• This is STRICTLY for a new battery service only. I cannot fix defective LED light issue, bad button issue or a dead/defective logic board inside. 
• 30 Day full warranty on a new battery performance (will typically run your iPod shuffle over 20 hours after a full charge).
• PLEASE SHIP immediately your iPod shuffle 2nd gen in need of a new battery so that the whole process won't take too long (I selected my handling time as 20 business days as I have no idea when I could get your iPod shuffle to be fixed).
• If you really want to UPGRADE the cosmetic condition of your iPod, I might consider accommodating your request at extra cost, thanks!
