Great bags
This bag held up well in the pressure cooker (Instant Pot), they are an ideal size but can struggle to fit in the Instant Pot if you fill it too much. They lack an injection port which is the only down side.

Despite what some reviews say, these bags didn't melt in my pressure cooker. I made sure they were lifted off the bottom and that my cooker didn't run dry and they worked a treat. Totally able to use them for fruiting blocks.

These were a good size and the filters seem ok but a couple of them seemed to lose their shape after pressure cooking? Not sure if it was something I did wrong or the bags not coping well with the pressure?

These are great. Quality made and solid. thickness is standard- these are easy to use/seal. (If you don't have a heat sealer, just tape shut with micropore tape. If you don't have that, then just some clear box tape (like moving box tape) They are great at keeping moisture in without being too wet, and the filter patch is perfect. You can slowly push air out of it once your substrate is inoculated.

While the thickness doesn't feel like 6mil, these bags are solid. I ran one through my insta pot for 90min and it worked flawlessly. If your bags are exploding, you need to heat seal them better. The bags are quite big and definitely a good value at $0.50/bag. Will buy again for sure.
