Packaging is always the first thing I notice in a product.  This slower cooker is packaged well & the box it comes in is quite nice looking.  I first tried this as a regular slow cooker and was pleased with the performance.  It works like most Crock Pot brand slow cookers and maybe even a step up.  The food was prepared just right and I was pleased.  As for the sous vide option, it is ok for a novice sous vide cooker, which I certainly am.  I don’t have a lot of experience with it but thought this was ok.  It eventually did the job but isn’t extremely advanced in the way of sous vide cooking which I’ve done a lot of reading about.  If you are just getting started with sous vide, I don’t think you’d be disappointed in this cooker.  If you are advanced, it’s probably not for you. Overall, a good slow cooker by a trusted brand.
