Not bad at all.
These are actually pretty darn good for made-in-China generics. They withstand strong suction and injection pressures (measuring & dispensing small quantities of epoxy), and the rubber pusher/seal doesn't fall off or separate. The only nit I can pick is that the "wings" on the body of the syringe are somewhat more flexible than brand-name American manufactured syringes, and bend under strong pressure. But these syringes are less expensive and available on Amazon!
