...this little product, then surely mobile phone makers would employ this 'technology' in some form - creating phones with better signal capacity, and that cope well in weak signal areas is the holy grail of mobile phone production. But, I am an optimist, and I fell for the sales hype. Also, it is only a few pounds, so thought it was worth a go. Maybe there really is some undiscovered technological worth to this product? My Sony Ericssons were out ...
...increase of signal on the mobile phone. It can increase it, even if it's just half a bar, but because it's half a bar, it just doesn't show on the phone. A rather convenient claim. Another part of the sales patter: after long paragraphs of hard selling the virtues of this products, is, 'it might not work for you, but for such a small outlay, it's worth a go". Again, another classic sales tactic. Indeed, this is what this product seems to rely on, ... Read review

...dirt that would prevent the Mobile Phone Signal Booster from being applied properly. Try and apply the booster on the flattest part of your phone, near the centre of the phone as possible but avoiding covering your sim card. Be sure to place the booster with the "top ^" sign facing in the right direction. The booster is less likely to work if you install this incorrectly. Fit the battery back and place the back of your phone in place. Whilst doing ... Read review

These things simply do not work. I have tested them on a range of phones and they have made absolutley no improvement to the signal reception. They sell because they're cheap and people think it's worth a punt at the price, but we're all just wasting money whilst someone is pocketing a tidy sum - probably the same people who write the rave reviews for this piece of trash.

Advantages: Increases signal up to 3x.Easy to install,less droped calls
Disadvantages: None

...get dropped this is a must . Every one i know now has one of these in thier mobiles and some spare. The cell phone booster is a passive device designed to capture stray radiation in the body of the phone and re-radiates the signal to improve the phones performance.

I have tried using these on several different mobile phones and they offer no improvement at all. Everybody else who has tried them that I have talked to agrees so I can only assume that the 5 start reviews that keep getting given are only done by the people who are selling them. I bought them because I thought it was worth the risk at such a low price but believe me it isn't. Stay well away!
