If I am taking .5ml ED, yet drawing traditionally a bit over .1ml is wasted ED in the pin/syringe.. for every 5 doses I lose over .5ml, which is 1 dose... do this for the duration of the vial, you lose about 4 doses... I got 15.5 out of my last 20, and I measure it to .5 exactly everytime, and yes the vial was full
This is why it is a concern.. why trash 20% of your gear when there is a better way?
I guess I must have other issues such as common sense and not wasting good gear
If you don't mind throwing out 1/5 of your gear..
