We have a B2B tagging system, which was installed 2 years ago, and have had no end of problems with it in as much as the aerials frequently fail to work thus making the system useless. Has anyone else had any problems too, as we are having extreme difficulty in getting the problem rectified....? I'd be very interested to know, and very interested in any comments you may have regarding this system. Or, if you have a brilliant system that never fails, then I'd love to hear too. Thanks.......... Jan
