@scottyfromscotland: Unless the “hand drier” was provided by Cambridge Theranostics, and you received a prescription for Ateronon thanks to the results of its beckoning beams 
As to the cost of this proposed MIT-hand dryer, if one adds up cost of test strips used in a year, there’ll be more than enough cash in the NHS coffers if they don’t have to be bought at all – or would there be need to calibrate this machine (like with CGM ?)
