My diabetic nurse is about as much use as a chocolate teapot - whatever I ask her about she will give me such a vapid answer that I get no help. Her answer to the meter was, 'well what if you change you mind about how many carbs you are having? You can't change it' so she wouldn't set it up, didn't know how to set it up any way and I phoned Abbott and we did it together as I am a bit thick. I love that you only need a tiny bit of blood on the strips, but I really struggle with getting the strips out of the little container. I have to say, Abbott have been really helpful and they phone and ask you stuff too.
