Query: somewhat tricky project -- with satisfying results

When my daughter's iPod mini lost its ability to retain a battery charge, I first checked if I could "outsource" the replacement project. Yes... but at too high a cost. So my research on other options led to this Sonnet replacement pack. The written reviews I read were inconsistent -- some reviewers found it easy, others found it impossible. I reviewed the Sonnet demo video of the process and thought: I can do that.Heating the end pieces of the iPod mini with a blow dryer and prying them off with the small tool (provided in pack) was the hardest part, and somewhat tricky. But by observing the cautions in the instructions (don't scratch the screen!) and carefully following the demo video (hey, this battery has printing on the opposite side!), I successfully completed the replacement.working iPod = happy daughter; economic & successful project = happy dad.
