Title: It worked but the installation instruction was challenging
Review: I brought this battery for my iPod mini. After I opened it, I found the installation instruction was for the iPod Classic. Undeterred, I went to cnet.com and found a 3-part videos on how to replace the battery on a iPod mini. For me, I prefer video over little text any day of the week. The videos were great, still it was difficult to replace (be very patience and little coaching help), and eventually got it working nicely. So, 4 stars for me.
