Query: the best skin I could ask for...

After researching online for a few days trying to find the 2nd gen Nano skin I decided to go with zcover, even though I did find some negative reviews on it on other sites. I am glad I didn't listen to them because this is the perfect one! It offers excellent protection covering everything - the screen, the click wheel, the charging port. I was worring that the clickwheel protection might not be sensitive enough and it would be hard to scroll, but it actually is thinner than the rest of the body. I did not have any difficulty scrolling at all. And I like the fact that it is somewhat clear, so my green nano looks very pretty through it!
