Hello.I have a question.Is disposable insulin feathers that are not smart?My son was given the intelligent in Social Security, and in less than two months he has lost/stolen 2. They are faces, so it is not a matter of leaving the payroll recovering it.Shortly 3 months go to the United States, so to carry all insulin it is much more practical cartridges with reusable pen than to load with so many disposable feathers.If there were rechargeable feathers without technology, more affordable, it could carry some spare.Thank you
