These syringes are pretty good and super cheap! I think that the special coating helps prevent bubbles, because I haven't had any problems with them- unlike with much more expensive syringes. The only reason why I am not giving it 5 stars is that it doesn't have half unit gradations, which would be really helpful for dosing my cat.
I have had great results with this type of syringe. The needle is ultra sharp as my dog doesn't flinch when receiving the dosage of medicine. The price is very competitive for equivalent products online.
