I never thought I would become a "syringe snob", but these have made me one. Prior to ordering from Countryside, I would just get some from the drug store. While they functioned, I often struggled with drawing the correct dose. The plunger would get stuck, then suddenly move and go to far, etc. The Advocate syringes are so much nicer. The caps are much easier to remove...no more bent needles! The plunger moves smoothly, so no frustration with getting the correct dose quickly. These are great! I'll never buy another brand again!
