Type 1 for 47 years. My accuchek expert has stopped ( apparently now obsolete ). I rang the company who are sending me a new chip, if that’s no good then a new meter. I’m currently off after surgery on my hand so everything is difficult at the moment. My carb ratio is 1:10 and cf is 1:3 ml. Does anyone know of a good replacement meter that gives bolus advice? It couldn’t have happened at a worst time x
