Hi all I am currently doing my GCSEs and have had all my remaining sensors fail so I can't use the system. Out of the last 5 sensors - 4 have failed (it was obviously a defective batch). Abbott are going to take a week to replace the sensors and I'm desperately looking for someone who has a spare one I could buy off them so I can go into my exams with the best control I can manage. I have an exam every day next week. Does anyone have a spare sensor I could buy? I live in Sussex but will travel to get one if necessary. Here's hoping...
