Review title: Didnt even notice it for all 3 months, not real metal.
Product review: I got two of these free with some chintzy cell phone accessories and installed them in my wife's and my cell phones. I didnt want to but she seemed to think it might be stylish. They did nothing of course. I totally forgot about mine. I took it out after a few months while doing a battery swap, and haven't noticed any difference what so ever. No fewer or more dropped calls, no better or worse call quality.Upon removing it, I noticed the "foil" was see-through when put up to a light and probably isn't even metal, just cheep gold paint. I thought it would at least be that thick copper foil you see on those anti-theft devices they put in everything at the store. I guess that would ACTUALLY affect call quality, not in a good way either.I should try making one of these out of real metal and see what happens, hehe.
