Customer Rating: 
Summary: Didn't help my poor reception phone much.
Comment: Have bought one of these years ago, but this one did not do much of anything for my reception problems and dropped calls with my Samsung slider phone. Worst reception phone I have ever had, and was hoping this would help. Did raise the bars in some places, but not enough to solve phones internal antenna problem. ..... at least it wasn't too expensive. If I remember, I think it did help phone of past that was a Motorola flip phone.... if that helps ya.
Customer Rating: Summary: not that good
Comment: I ordered it in hopes that it would do something, but im convinced that it serves absolutely no purpose. However in an attempt to sound fair, it might have raised the bar by one level, but i just don't think so.
Customer Rating: Summary: Can't go Wrong
Comment: Can't tell how much this antenna really helps, but it doesn't hurt reception in any way so for the price you can't go wrong. They are still sold in the stores for 10 times as much.
Customer Rating: Summary: not functional
Comment: I thought I'd try this since I was desperate and it was cheap, but as someone who studied engineering, I really should've known better. Whoever created this has got to be relying on the desperation/gullibility of people. How in the world is a thin sticker, no matter what's painted on it, supposed to catch some ambiguous "rays" and use that to boost signal? Just think about it.
Customer Rating: Summary: Is it worth the money? That depends...
Comment: This is VERY inexpensive: it costs a penny, and while the shipping is far too high for an item that could be slipped into a first class envelope, it's still relatively inexpensive.
That's why I tried it. I figured that I wouldn't be out too much money.
Does it work? I'm not sure. I haven't been able to conduct controlled experiments - only a scientist could - but I can say that it *seems* to give the phone the *tiniest* of boosts.
So, it depends on how much you're willing to sacrifice for a tiny, and almost imperceptible boost in signal strength (if there even is one; the boost I noticed could easily be a product of my hopeful imagination).
As for me, I wouldn't buy one again.
