We dont know - so why tar them all with the same brush? It would be simple to give people the meter and strips for a month, for example, and then review it, and ask for the meter back if they dont use it properly. Knowing the meter is on loan would stop these people selling them. How many of them do that anyway? I suspect it is only a few, or the market would be flooded. I know the meters couldnt be given to someone else, but it would stop the trafficking. Dont meter have some sort of notification or record on them of whether or not they have been used, and the figures? I am sure my dads meter did.
