Hello. I use a 25 qt. Igloo brand marine cooler with a removable lid. I cut a hole that is the same diameter of my Annova in one corner of the lid. Rinse, fill with water, add desired vacuum sealed food, slide my Annova in to the hole, and set it to the desired temp. The cooler is lightweight, very well insulated, and easy to move with the handles. Got the cooler for $25 at Walmart. It is the perfect container for me and large enough for everything I cook, from multiple steaks to large, whole roasts.
