I use the autoinject. Been on it since May, and I've gotten better at knowing where to shoot myself. But I've had some award winning site reactions in the beginning, and if I'm a little off of the "good" areas to shoot in - I get a wonderful red welt.

Not sure if the reactions went down because my bod is getting used to the medicine or because I make sure to wipe the injection site with a warm wet washcloth to make sure no med is on my skin.

I've lucked out and haven't had any dull needles yet. I do always make sure the med in the shot is clear. I disposed of one syringe because it looked discolored, but that only happened once. The nurse who came out advised that any discoloration or if there was something that looked like dandruff in the med means that syringe should not be used. If more than one in a box, report to Shared Solutions immediately.
