The best refillable pens out there are the ones who use both
springs and mechanical tension and not simply mechanical tension. If you've ever used a
disposable pen auto injector (GLP or some other medication), you would realize just how smooth these are.
These pens simply require you set the dial to what you would like to inject, and then press ONE button. The mechanic pens are the ones who require multiple clicks, one click for each drop. Whether its metal or plastic (on the outside), doesn't really matter.
Sadly, almost all pens out there are based off mechanical tension, because they are much cheaper and easier to produce.
I have since swapped my Humalog Luxura HD to GensuPen2 which uses the same lily cartridges / pen needles. The one click button is on the side. The difference is night and day. I also avoid anything Novo related due to how they use special cartridges.
TLDR: Look for these keywords.
Plastic/metal is irrelevant.
(1) Spring-assisted / Spring-based
(2) Reusable
