FWIW I had successive "wet strip" Errors with the first meter I had with my pump Alan. My hands were never wet. The middle of my dining table and the inner reaches of my handbags had not sprung leaks. And different tubs of strips. And a new scrip and different batch numbers etc etc. Roche kept saying it was me. I kept saying I've been using a Glucometer now since they invented em practically, please don't treat me like an idiot.
Eventually I rang after hours - a Saturday night - because the out of hours pump helpline is manned by a more intelligent species than the one I actually kept going through to during office hours.
Within 20 minutes, they'd agreed there MUST be summat up and agreed to replace the meter. Which they did.
And curiously you know, the specific person who I had the trouble with, has never ever answered the phone to me again .....
