These are reasonably priced and perfect for administering your insulin.

Great. I ran out of the ones I received from the doctors office and then quickly realized I’ll never use those again. These are technically the same gauge and length as the ones I was given, but are so much better. I don’t even feel them when I’m injected. Not sure how that is, but I’m not complaining.

Gets the job done. Really good for the price. There are some needles that suck but what can you do? Usually about 3-4 are bad, meaning after I insert it in the vial it bends so I have to change it.

I'm always looking for quality, effective syringes and these definitely deliver. Very pleased with this 100 pack. The size and markings appear to be accurate. The plunger is smooth and easy to deploy, and the barrel is durable. The needles are very sharp and are burr-free, no pain using them at all. I love the individual packaging, it seems so much more sanitary to throw a few of these in my travel bag instead of loose ones floating around. Definitely adds to the overall value of these, which is superb.

These syringes do exactly what I need them to do without any hassle. The needle is very fine, which makes a big difference with comfort, and the size is perfect for the amount I use. Everything feels sterile, well packaged, and easy to handle. The plunger moves smoothly and gives good control without sticking. I honestly appreciate how much easier this makes the whole process for me. When you have to do shots regularly, the little details really matter. These take a lot of the stress out of it and make it quick and simple. For anyone who needs this size and gauge, these work great. Integrity Tested

I like that these are individually wrapped, which make them easy to travel with and still be assured they are sterile. Easy to open (tear at topl, functional, and decently sharp. The plunger does seem to pull in a little more air than some other brands, but not enough to make it a hassle. I always disperse air from the top no matter what. I like that these come in 0.5ml, making it easier to pull smaller doses. The dosing lines are easy to read and accurate. Great price for 25 of these, no issues.

Not much to say here. They are pretty standard syringes. They come loose in the box but are individually wrapped. Full disclosure: I am not using these for medical reasons. I'm using them for various projects that need resin or glue. Since they are plastic, they are one-time use for glue-related projects, but as long as the resin doesn't harden, I can use them a few times before getting clogged. I have also used them for paint mixing when painting miniatures, so that I can keep track of how much paint is used when mixing. Since its acrylic paints, I can reuse them longer by just running hot water through them. This makes them easy to use and reuse. They are durable enough for these projects, so I assume that in medical use, where you wouldn't reuse a needle anyway, they would be just fine. Since you get 25 of them, I think they are a great value, especially when you put something through them for projects that is easily cleaned.

Quite a few of these clogged. I’ve bought before and they were great but this batch wasn’t.
