UltiCare VetRx U-100 Pet Insulin Syringes, Comfortable & Accurate Dosing of Insulin for Pets, Compatible w/Any U-100 Strength Insulin, Size: 3/10cc, 31G x 5/16’’, w/Half Unit Markings, 60 ct Box

Just ordered my 17th box. These syringes have always worked great for getting my cat the insulin he needs daily. Never had a single issue with the quality of the needles. I think the box is a solid value... the syringes are very well made and they work excellently. If only everything else in life was as reliable as these are.

Our golden retriever, Ed, had diabetes for about five years and these are the syringes we used. They worked well and real convenient to set up on subscribe and save. Ed passed away a few months ago so we unfortunately no longer have a need for these any longer.

used off label for myself (beauty injections) painless, precise, affordable & ez to use👍🏼

Great purchase for my diabetic cat. Works perfectly for a lower price than what is available at the vet.

I love these, they are accurate and have 1/2 line marks. I bought a "pharmacy" brand for years for my diabetic cat but once COVID hit their needles are not being checked for quality assurance. Needles are not always the same length with the "pharmacy" brand.

We use these all the time perfect for insulin diabetics dog.

I have this delivered every 3 weeks because I have a diabetic cat. Occasionally, there will be a needle that's crooked, but that's few and far between and hasn't happened in the last couple boxes. The draw on the syringes does often push insulin back into the phial (other reviewers mention this), but I usually draw back a little and everything works out. The half-unit marks are very nice, as well. The "bulk bag" packing, where there are 10 syringes in each package in the box, is fine; however, I would prefer (for boarding, travel, etc) if they were individually packaged. But I will continue to order/have these delivered because they are easy to use and the differences between lots are easy enough for me to deal with.

My cat has been diabetic for a few years. These needles are perfect. Short thin point. He tolerates them well.
