"They Do Pop Off"
Had the same thing happen as another reviewer, using the same product (injectable ivermectin). This medication is fairly thick and rather oily, but I was using an 18g 1" luer slip needle on a Jeffer's luer slip syringe. That gage needle should have been way large enough for the viscosity of the med. These hubs are way too loose and don't have enough grip.
I read the other review and have been buying boxes of needles (several different sizes) from Jeffers for several years now. Never had a problem, they did their job. Generally, I use Luer Lock Syringes, but occasionally I don't...never had a problem. Great quality for the money.
Tried the 20g 1/2" needles on Jeffers 6 ml syringes for ivermectin plus, and they popped of the syringe as soon as I tried to inject. The hubs are way looser than the others I have ordered. I have a nearly full box I simply can't trust.
