What are recommendations / improvements for diabetic devices and equipment?

Hello members,

Diabetes is condition that requires changing one's lifestyle to an extent and constant monitoring. 

Along with that comes various types of medical devices and equipment dedicated to making this easier, from insulin pens to insulin management systems and blood glucose monitors.

Are there any recommendations you have (or wish existed) or improvements that you wish would occur in regard to medical devices and equipment for diabetes?

It used to be for me the ability to measure blood glucose levels without the need of "pricking" the skin, but thankfully I discovered the availability of these devices last year.
