I'd like to hear user experiences with Nipro brand syringes. So far for me, the regular 3cc syringes have been decently good although if you hit a vein and have to draw out, good luck trying to get it back in. It's like they use the softest metal so even piercing the skin one time seems to blunt them easily. Now the new slin pins they have look pretty cool. They have engineered them to have no dead space which is undoubtedly awesome. But again with the soft metal and easily blunted problem. Especially since you have to use it to pierce the top of your vial, and going through the rubber stopper blunts them so bad that I can't get them through to inject at all in most cases, at least in the batch that I recently bought. I'm hoping that they'll harden these buggers a little more in the future so they are resistant to blunting. Terumo still beats them hands down when it comes to staying sharp. I just wish they didn't have the dead space. Considering how much they blunt, I'd just rather pay the higher price for Terumo and lose a little bit from the injection rather than try to poke myself with a unsharp piece of metal.
