That being said, I do really like the fancy needles we got in a small quantity while waiting for the cheap ones to ship. They're too big and I was really sweating about that. But they actually go in so smooth and reliable! You'd hardly even notice the extra girth. Going back to the cheap ones with the high defect rate, where I've had weeks where I had to go through three needles to find one that actually works (only way to know is to try, and find out if it really fucking hurts), that's probably going to suck. But the price difference is insane. The nice ones are financially impractical to purchase in quantities more than like... four.
