Insulin rechargeable feathers

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

Before they gave you the empty feathers and sold the cartridges.They were more precise in the administration of insulin.Now I believe that all feathers are pre -filled and they are to UAR and throw.
