Is it worth the money? That depends... 
2008-02-10
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.
I aint saying it's a piece of junk....

I aint saying it's a piece of junk as it may work on TDMA/analog phones but it did nothing for my Nokia on a CDMA network. I live in a small rural village that doesn't have a stoplight or very good cell coverage. I get one bar for signal strength. I found these for sale for fifty cents each plus a couple bucks postage, so thought I'd give one a go. Nah....I still only get one bar. I wish it worked but it doesn't...welcome to my world.
Can't rate it if I don't have it.

I never received this product, so I can't review it. After several very frustrating phone calls to the third party vendor, which accomplished nothing, I did receive a refund from Amazon. They did honor their guarantee.
Do not waste your time.

Simple stated, it doesn't do diddly.
Do not waste your time and effort on this product,
unless you are a big fan of shiny stickers that do nothing.
Good product

Features:- Works on any digital or analog cell phone, pager, wireless telephone, PDA, etc, as long as you have access to the battery compartment. In some cases, it may be applied to the back cover of a device, behind the battery (like in PDAs). - Boosts reception virtually anywhere as long as there is at least ½ bar of antenna power.- Static is reduced- Easy to install- Each booster is individually packaged- No tools required for installation How does it fit?The Antenna Booster is easy to install. It comes with its own backing self-adhesive sticker. Just slip it underneath the phone's battery, and enjoy clear, enhanced, static-free reception. How does the Antenna work?The Internal Antenna Booster is a passive device designed to capture stray radiation in the body of the phone and re-radiate the signal to improve the phone's performance.The Antenna will work most efficiently when installed properly to reduce static (analog) and momentary cut-outs (digital) and increase clarity. Will the Internal Antenna help me get reception in dead zones?No. Despite what other resellers may claim. The Antenna Booster enhances a signal that's already in the area. It will not bring in a signal where there is none and cannot improve battery life. What models does it fit?It will fit all models except Nextel 500 & 800 series and any models with a screw-back battery compartment.
These work!

As long as it's this one and only this version! The ones I bought under a different listing on amazon do not work at all. Warning to all, if you want the ones that work, include 'gold' in the search.
