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.

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'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.

The box is misleading, it shows a photo of a 1ml syringe and doesn’t specify what’s actually inside. Fortunately, the individual syringes are correctly labeled as 0.5ml/cc 31G 5/16" and are individually sealed. I use these for peptides. It’s also confusing that the box says “for subcutaneous injection of insulin and over-the-counter use,” while the product listing states “not intended for professional medical use.” Clearer labeling and consistent information would be appreciated. Syringes work as expected.

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.

Exactly what I needed for my weekly injections! 100 per box. Individually packaged, compact size, easy to use and appears durable. They serve their functional purpose, sharpe and durable. Great value for the money.

The fact that these syringes are sterile and individually sealed immediately inspires confidence. They are well-made with a sturdy plastic body and clear markings for precise measurements. The smooth plunger action is a game-changer for dosing accuracy, and the fine, sharp needle ensures a virtually painless experience. Overall, a great investment and my new standard.
