I’ve always wanted to have a sous vide machine because it allows you to cook food to safe temperatures (while marinating) easily without losing moisture, but they’re ridiculously expensive. This thing takes up way less room than a conventional sous vide machine. You can use any pot you have lying around and you can control it from your phone. You can just put your meat in the thing, go out all day, start cooking while you’re out, and come home to a perfect steak in minutes. You need a vacuum sealer, of course, but after throwing it in a pan for a minute, you’re going to get the most perfect fish/steak/pork imaginable.
