These are excellent. I have given thousands of injections having been an ER nurse 23 years. A very sharp needle aids for comfort of the injection & it should slide thru the skin without resistance. Even after sticking these thru the rubber on the insulin bottle, the needles are so sharp it slides thru my kitty's skin. I am so very pleased with these syringes.

Mono jet syringes

These syringes , U- 40 1/2”, are very easy to use and accurate to draw up insulin. I would highly recommend them.

Good Quality, Easy to Read

Hard to read

It’s hard to pull for me anyway I have to pull it open first. Then do the insulin. Also hard to read the line.

I guess I'm stupid

I was looking for 1ml syringes for a B12 injection, the markings for these syringes are not in milliliters but in units. Attached photo shows the syringe from my vet with milliliter markings and the syringes from this product with units. I guess the U-40 on the box indicates the syringes are 40 units, so I guess I am stupid, but I'm writing this review in case others are confused.

more careful next order

Should have ordered something w/ smaller syringe and larger spaces between hatch marks. Hard to see the 0.5 cc, as there is no marking for that and the hatch marks are very close together. Sorry to add, the action is hard on these syringes, plungers doesn't move easily nor smoothly inside the barrel. The needles are good, short and thin. Would work well for larger doses in whole cc's.

Good product good price

My dog recently was diagnosed with Diabetes. My first box of syringes was another brand and was over twice the price for same amount of syringes. As the amount of insulin needed to regulate my dog got higher and higher I needed a syringe that was wider and could hold the amount. This meant less time of needle in dog and easier for me to push insulin in. The vet recommended Monoject. So glad I tried these. These work wonderfully. Why pay more !

Diabetic Cat

These syringes work great, although my cat Dusty is a little scared when he sees the needle but they are very easy to use and it is over in a second.
