You believe Consumers Reports? Really, one example they tested oil filters. They used all of the standard test from SAE. Then they created their own test, the poured oil with "Arizona road dust" into the filters under no pressure, just poured it int through the holes and poured it out again and measured the "dust" and declared one filter the winner based on this test. The standard engineering tests found most filters to be tied. This is Consumer's Reports testing. It is a nice guide, but as the basis for a decision, I would run from it.hopefull transfer from iphone to mac can solve itNot just sliders, all tight fitting hard cases that are direct plastic on glass. My iPhone 4 now has a small chip on the back glass from a piece of dirt or something getting stuck in my otterbox defender. It had been under the felt part. I recommend getting a candy shell or somthing similar that has a soft material in contact with your phone.
