These are absolutely the best needles I have tried. I used the Monoject 20's from the vet and had some moderate success, but the insertion was painful and the flow was slow. I then tried 3 different sizes of Terumo needles (19, 20, and 21) and although the insertion was easier, the flow rate was very unpredictable. I've been using the Monoject 19's for 4 days and it's like night and day - insertion is a snap and flow is super-fast. I can't believe how much easier the subq process is for both me and my dog. All I can say is give these a try!
