And that DO NOT require a code book? I'm asking because someone on another site has a relative just diagnosed with type 1. I recommended a scale but it seems the 1450 is no longer available and any others require a code book. We had one like that for a short time and it was such a pitb compared to the Salter. Also ours has been acting up lately and I'm worried it will need replacing. I don't want to have to go backwards. That seems crazy in this day and age.
