I carefully cut out the corner of the lid, making sure to not crack/split the plastic so the ISV-100 clips on the tote. A dremel cut off wheel or hole saw for a starter hole is good. Marked the outside of the tote with a sharpie for min/max SV water levels. I like the clear tote to see the weight blanket holding food down ( vac sealed flat glass gem beads from the dollar tree.) Used a hand towel to make a gasket around the SV. I usually keep it on the floor with a towel over it for insulation. You can remove the lid and pour condensation into the tote at the cut out corner without turning off and removing the SV.
Small mason jar . I put graham crackers on the bottom . Leave the lid on the jar a bit loose so the air can get out . Haven't made any in awhile , but they're good .
