I keep buying them because they're that good!

I love these syringes! I know I can count on their accuracy, especially when I need to dose, for example, a 0.75u for my cat. I tried the 30 gauge and found them to be great and equally accurate, but my cat prefers the 31 gauge. We are happy campers using all things Advocate!

Best syringes on the market!

I am deeply impressed with the consistent accuracy of Advocate U-100 syringes with half unit markings! I dose micro-doses, so having tried every syringe on the market with half unit markings, I finally found Advocate and will never buy any other brand. I feel peace of mind knowing my little diabetic cat is getting accurate dosing.
In addition, the President and chief operating officer of the company took time out of his very busy schedule to spend an hour with me on the phone, telling me how to make the switch from the meter I was accustomed to using to the Advocate Meter, and once again, I'm impressed! I love the non-corporate feel to Advocate, the mom-and-pop feel to it, when the President takes time for a customer. Clearly, he and his company care deeply about their products and their furry patients, and they have a customer for life! I positively love them!
