Loads of these on e bay for about 40p each, anyone got one and do they work?
(seems unlikely to me).

will it work if i stick it on my bedroom window to boost the signal? :D

they are rubbish i think don't know about signal boosting but they just look ugly. they are made in places like china where you can get for about 5p! most of them flash.

For what they cost to produce, if they were any good, the mobile phone manufacturers would fit them as standard.
