Dull your needle for safety!
I have not seen this mentioned yet so I thought I might. As hypodermic needles are quite sharp and able to easily give you a shot of E-fluid by accident (Which I dont think anyone wants.) It occurred to me that a good trick is to round off the tip of the needle with a file. Dulling the needle to enough that an inopportune sneeze doesnt lead to an accidental injection is a very good idea and lets anyone who wants to inspect your kit know that it is only used for refilling.
Also, a curved tip syringe (All plastic tip syringe.) also works and makes a very good statement about your intentions. These are usually found in farm supply stores or your local veterinarian if you ask really nice.
