• 100% brand new.
• Fits ALL mobile phones: AUDIOVOX / ERICSSON / NEXTEL / NOKIA / MOTOROLA / SAMSUNG / QUALCOMM / KYOCERA / LG / PANASONIC / SANYO / SIEMENS etc...
• You should notice atleast ONE "bar" more than before. Keep in mind that in a near zero signal strength area (less than continuous single antenna strength bar), results will be minimal. In areas where cell signals are non-existent, the booster will have no effect (but neither would a 10 foot antenna)
• Improves sound quality by eliminating noises.
• Very easy to install. No tools needed. Just stick it to the back of the phone where the battery is placed into.

Comes with detailed instruction to use in retail packaging.

This is as effective as putting magnets on your fuel lines. It does nothing. I got one free with an accessory pack, the case and charger worked. Anyway, I tried the thing with three phones and it made zero difference. Not a single tiny difference. But I am an electrical and electronic engineer with 25 years experience, I make wireless internet gear for a living and I'm an Extra class amateur radio operator, so I knew it not only wouldn't but couldn't work. Basically you can't stick something inside the case of a phone and expect it to improve the signal for an antenna it has no attachment to. In many phones, like the Motorola v60i and Krazr I tried, this thing is inserted between the metal back cover and the metal chassis of the phone, there is no way it can do anything to the signal.

Laugh and move on. Keep your money. In Europe the vendors would have been fined tens of thousands of dollars for selling these things.

This product made no difference at all in my cell phone reception. Cell Phone is a Nokia 9300, service is through ATT

I found no difference whatsoever in signal strength after using this devise. I think its a total waste of money! If this actually worked, all the phone manufacturers would have started installing this before selling their devices.
SCAAAAM !!!

I've order 3 diferent antenna boosters but this is the best its twice as big compare to the others fits in my razor V3xx and i realy dont have any problems with droped calls or low recepcion inside my house anymore.

I've used these in 5 different phones since 1996. I live way out in a mountainous development. The low signal and dropped calls don't change one single bit when I add one of these to my phone. They are completely useless in my 12 years of experience.
