I didn't understand most of what you said other than you don't think
they work but I doubt that is true now that I've spoken to them a bit.

I don't doubt that these cell phone amplifiers are illegal in the UK
so I will set the follow up accordingly to remove u.t.m in any response.

I called UberSignal who said they work fantastically for all carriers.

I don't know why anyone would "hate them" because all they do is make the
signal better and it would seem to me for them to be unrealistic to sell
them 
if they didn't work, but that's why I was asking here who already uses them.
