Does anyone know how long refillable pens last? I’ve been using my Junior pen for 8 years and all the color has worn off, but I like that it does 1/2 units. I wonder though, if it has any loss in accuracy being that old?
I used mine for 15 years. If I ever go back to MDI, I plan to resurrect it and use it some more. I, too, liked the 1/2 units.
For NovoPen Junior there is a procedure described in the manual to check it for accuracy.
