As an owner of a $2k+ Thermomix (which can do sous-vide in a very confined and limited fashion) this interests me and $400 doesn't seem outrageous if it can become a regular tool in the kitchen. I do wonder how much is covered by a slow-cooker though.<p>Going on the TM, my concerns would be cleaning (doesn't seem like a big issue) and how much of a meal it can actually do.<p>With the Thermomix, we found it went from gimmick to regularly used device quickly enough - marinades, sauces, pureed baby food, mashed potato, etc. Besides weigh, heat, blend, etc it can also work to a set temperature (though with broader increments) and I eventually tried some steak sous-vide. Vacuum sealed bag, into the basket (to prevent the blades from rupturing the bag) and away it went. It worked OK though the steak obviously needed to be seared at the end. That left me rinsing the TM and still having to wash the pan/griddle, etc.<p>If you still need to prepare/cook your sides, I wonder how much time has truly been saved? I've had reasonable success with the slow-cooker too: one-pot dish so cleaning is easy, sides aren't much of an issue, etc.<p>I imagine that the value in Mellow will come once the community strengthens and people work out a set of go-to recipes that minimise other mess and prep.
