I don't know about you guys, but I hate wasting ANY amount of gear. I was wondering how you get that last little bit in the syringe. I'm afraid to pull back a bunch of air trying to get it out. My wife keeps telling me to let it go and start a new bottle. She says I look like a strung out junkie when the bottle is almost empty and I start tilting and turning it trying to suck in that last little bit of residue. Maybe she's right. :)
