Buy this one
Excellent. Exactly as described. Fits a 15/32 inch hole perfectly. Use a step drill bit for a super easy clean hole in a jar lid. Oreilly sells a kit that includes a step drill bit with the correct size. Best value for money. Excellent durability, I tested one by puncturing it 20 times. As long as you use slightly different spots it lasts easily 10-15 punctures with a 16 gage needle.

Worked flawlessly.
100% success with zero contaminates. No problems being pressure cooked at 15psi for 90 minutes. The ports can be used multiple times, but they're so cheap I use new ones each time. 100 for $10 is an excellent buy.

Game changers for liquid culture jars
These are game changers for liquid cultures for mushroom cultivation. Super cheap for how easy they make sterile spore and LC transfers.

Fast shipping and packaged good
Fast shipping product as described and great price. Can’t really complain but made of a harder rubber than the higher quality product vacutainer type. Would buy again in a pinch

Makes keeping a sterile environment easy
They work great. Be careful when using a hot tool to pierce it. The heat makes the self healing ability non existent.

The smell and thickness
This product was supposed to be used for gourmet mushroom cultivation, the rubber piece was very thick for my syringe which I felt was not ideal, they also have a very strong rubber smell that I did not appreciate.

Work good
They last longer then what I use them on. Price is good enough to use once
