Bank Statement checkers

Hi there

Has anyone bought bank statement checkers and found that their bank statements were incorrect?  I have been reading about them recently and there are lots of feedback on the various sites about how incorrect bank statements have been and how much money people have been able to get back from the banks.

I was wondering whether the feedback reflects the general consensus out there or whether the various producers of the programmes just publish the few rare cases of incorrect statements by the banks.

Cheers
