This is an updated model of two that are currently on 鶹 under the same name but different listings yet this one is newer and better priced, confusingly the product images/descriptions are identical and outdated because there's now a power button and different labelling. The large digital display is really appreciated because they're often too small or not well lit. Pressing the MENU button lets the dial scroll the different modes, TIME and TEMP lets you scroll your settings, when the dial is pushed in it starts/pauses the oven and automatic preheat will beep when heated and the timer starts and beeps again when complete. It heats quickly to max 450F but also dehydrator and ferment levels of 80F and the fan can be toggled to full on all the modes allowing "air fry" convection heat to whatever temperature or element pattern, six total used differently ie. two bottom/two top on bake, four top on air fry etc.
The build quality is excellent with a thick brushed stainless steel frame on all sides, actually identical to a Frigidaire model still available (who is making it?). Heat insulation is perfect without any problems to laminate cabinets on the sides or top, even within an inch. There's also insulation strips layered between the door but you'll notice forward heat coming out the crumb tray, maybe intentionally for flow. It's important to mention a review reporting the interior roof metal warping but it's the first thing I tested and didn't see any issue.
The non-stick coated tray can be cooked with but I think works better as an oil pan placed below the air frying tray or rack tray to avoid getting the crumb tray and bottom elements dirty, you can also line the crumb tray with foil. Because non-stick will scratch and deteriorate and is arguably unhealthy, I strongly recommend a "steel baking sheet with grid rack 12.5" x 9.7" by HaSteel or another brand around 12x10 without warping complaints, perfect for broiling and baking for around $20 and fits on the included rack tray you'd think Cosori (should have) included it too.
As for the optional smart connectivity through the app on Android/iOS, it also connects through Google/Alexa and Bluetooth is always on for connection. I would imagine someone thinking it was a good idea if they wanted to start it remotely and have some roasted potatoes ready when arriving home, but according to the manual, no. Remote control is only for after manually starting it, "for safety reasons", and generally seems to be for choosing a specific recipe within the app and locking in the settings automatically. You can also toggle things like the LIGHT and POWER OFF, temperature and time, but personally seems like too much and wouldn't you really need a camera to make it useful?
Overall, an excellent choice that cooks food perfectly, evenly, and costs much less in energy and time compared to conventional ovens. When new, I strongly recommend running at 450F BAKE with the fan toggled on for 20-30 minutes to burn away factory lubricants (typical for ovens and needs proper ventilation). If you notice the fan rattling (surprisingly common), try very gently shaking the oven on a slight angle once or twice while running only the first time. Otherwise, don't hesitate and just use the Return and Replace option. It should cost around $220 CAD (or $190 on sale) and supports a 2year warranty - more than most other options except for what I think is the closest competitor, the very overpriced large Cuisinart at 5year (apparently they make you pay shipping costs whereas Cosori generously covers replacement). Consider getting an extended 4year warranty on 鶹 for $30-40 rather than throwing money away after only a couple years.
