Exactly What I Needed, Quality Syringes That Deliver Every Time
This U‑100 1ml 30 gauge, 5/16 inch syringe pack (100 count) is exactly what I was looking for: sterile, individually packed syringes that are reliable, easy to use, and accurate. The markings are clear on every syringe, the plunger glides smoothly, and setup is simple whether I am measuring liquid for pets, garden nutrients, low‑volume lab tasks, or other precision needs. The 30G size with 5/16 inch length strikes the right balance between precision and minimal resistance. These are not flimsy or cheap‑feeling syringes — they handle everyday measuring tasks without bending or sticking. The 100 count pack gives plenty for repeated use without running out.  What Could Be Better: These syringes are clearly marked as not for professional medical use on the product page, so if your needs require certified medical syringes for injections into humans, verify that requirement before purchase. For hobbyist or non‑medical liquid measurement tasks this is great, but Amazon’s description includes that limitation. Otherwise these work exactly as expected.  Final Verdict: Five stars from me because they do what they promise: accurate, well‑made, individually sealed syringes in a large count that are easy to handle and reliable for liquid measurement. I recommend these for precision non‑medical tasks where consistent volume delivery matters and budget is still important.

Works for what I need.
These are a good value for the money. The needle size and needle length is as described. They are as comfortable going in as a needle can be. No leakage from the needle. I do wish the syringe was a little bit thicker and less flimsy.

Good quality for price.
Correct size that I needed. The needles are a little flimsy and could bend so make sure you go in nice and straight. These seem ideal for single dose needles. Easy to read and use.

Exactly What I was looking for
This was exactly what I needed. Shipping was fast, and each syringe arrived individually wrapped and in great condition. The 0.5 ml, 30‑gauge, 5/16" syringes are actually better than the ones my doctor originally gave me. I’ve used three out of the pack of 20 so far, and each one has been smooth and virtually painless. The measurement markings are clear and easy to read. I’ll definitely be ordering more.

No waste!
Ordered these because I ran out of what the doctor had given me. These are better! There was no waste (liquid left in the syringe after shot) unlike the syringes I had been using. I will buy again!
