1: Works as advertised. Air Frying really keeps me from using external food oils on meats & fish. Recommend placing a sheet of aluminum wrapping down before putting food in, if you can't bother to cleanup. After cooking, just grab it out & throw. (use 2 sheets if 1 keeps puncturing & spilling oil) Also works on defrosting & directly cooking frozen foods too. The intake is around the top panel (all 4 sides of it). The exhaust is out the back (1 rectangle). Don't block either of these areas. Core functionality is not gated behind internet. (VERY IMPORTANT) I didn't really care for the presets. A temperature control & timer was all I needed, and this had it. 2: Easy to clean the main components. (With exception) The bottom half of this product, which contains the pan & base, are really easy to clean. The coating is legit. A sponge with a bit of detergent, and all the oil goes right out. The pan was not built to hold large amounts of liquid however. I couldn't put a lot of water + a bit of dishwasher detergent in, expecting it to slowly remove all oils. It leaked out the bottommost screw hole's height. (Out of designed usage) Unfortunately, the top half section that contains the heating element & fan, cannot be accessed or cleaned properly by disassembling this product from below. 3: Excellent customer service!! As I kept using it, the top segment (the unwashable part) inevitably got dirty with food stains. I then decided to disassemble it to clean it. The top looked impenetrable (no screws out top), so I tried disassembling it from below. The air fryer did not permit me access however, so I contacted customer service. I requested a tutorial on how to disassemble it so I can clean the component. They sent me a video of the factory floor with workers just outright hacking away at the top with a flathead driver, which popped off. Well if that's the legit way to clean it, I love a direct answer. There could be possible improvements to the design that permits cleaning the heating element & fan without taking apart the whole thing, but as far as maintenance goes, showing how it's done is the best customer service I can get. 3: Flaws Access to heating element & fan is difficult. If I keep the pan in the device (after a cook -> take out to eat -> wash -> put it in without food), the LED display remains lit forever expecting an order. Might want to consider putting a long timer to dim it out?
