I'm sure I'm not alone in my obsessive compulsive treatment of my precious iPhone (especially the screen). Anytime I finish using or browsing through the many things my device is capable of (no need to focus on it's minor - and very fixable- omissions) I immediately use the included wipe to remove the smudges I have inevitably created... NO MORE!!! I installed the Invisible Shield today to ensure I wouldn't be the next unlucky poster sadly announcing the most recent scratch or chip. To my surprise (it hasn't been overly mentioned on this site) my iPhone no longer accumulates any fingerprints (well almost any)... AMAZING!!! I highly recommend the Shield. I can't say much about the scratch resistant part (no way am I performing the reviewers key or harsher tests), I believe their claims, and I will let time and use prove them wrong or right. If others have used different covers, let us know how they measure up on the smudge test.
