Is this Ninja kitchen appliance worth it for your kitchen?

How this Ninja kitchen appliance sears, braises and crisps in one pot

Here's what I'd want to know first: why can this pot go from stovetop-style searing to a five hour braise to a 500 degree oven blast without cracking, when most slow cooker inserts can't handle direct heat at all. The trick is in the base. Instead of a ceramic crock sitting inside a heating jacket, the aluminum pot itself carries the bottom heating element, so you can sear proteins and sauté vegetables right in the cooking vessel, no skillet required. Ninja calls the combination of bottom, side and steam heat triple fusion, and the practical effect is that the same pot handles jobs that normally need three: brown the roast, drop to slow cook or braise for hours, then slide the whole thing into your oven, up to 500°F, for the crust a slow cooker alone never gives you. That oven safe rating is the part that actually matters, because it's what lets one vessel finish a meal instead of just starting it. Layer on sous vide and proof settings and the 8.5 quart capacity, big enough for chili for twenty or pulled pork for thirty sliders, and this stops being a slow cooker with a new name and starts being a genuine stand-in for a cluttered cupboard of single-job pots and pans.
