Anyone try the new bd retracable pins?

[HAYEZ]

ya there pretty dope...absolutely no waste of oil..the plunger has a tip in it that seems to retract the needle once you have fully injected...im kinda sold on them and at 25 cents a pop at my local pharmacy isnt much to complain about hahaha

needto i also pull in about 1/2ml of air to aspirate and works great!

They're cool, but I probably would never use them. Only real point to them I see is helps keep from getting an accidental poke.
