Dual zones for smart cooking, but baskets are small.

I’m using similar model (but with the little window) for a year, and it’s still pretty good.
hi one year after purchasing, I’m cleaning it gently with kitchen metal scraper, and it’s still as new
I have extensively used a Nuuk. Very nicely made. More premium than the Philips NA221 at that price. The ratings are excellent as well. Note that it uses a 16A power plug vs others that may not. - All the features like Shake Alarm are thoughtful - The touch response of the controls is excellent - The device is nicely air sealed so it crisps really well (right up there with or maybe bit better than Philips. The base plate has a similar design as Philips to maximize air circulation). - Fries consistently have an audible crunch vs cheaper products. The inner and exterior texture of any food like poppers or fries is excellent. Phillips NA221 may be as good but this has been excellent and worth the step up from cheaper ones. - The crisper plate is nicely designed and easy to clean so the ceramic coating should last long enough.
Lol. That's really respectful. Anyhow. FYI you're in the minority. I run a whatsapp geeks group of 865 folks across IIT and IIM. Dozens of us who are fans of the brand there and hold similar opinions. Across a variety of products. Not denying amazon reviews just sharing my POV. Maybe I'm in the honeymoon period but honestly, how can you trash my lived (early) first hand experience basis some amazon reviews? Both instances can Co exist? Some got lemons some didn't.
If avoiding PFAS is the main goal, the Ninja Foodi Dual Zone AF300ANZ is worth a look ,ceramic coated basket, so no PFAS concerns, and it's a proper basket-style unit (not a glass/oven type). For the "keep it simple" brief, the Philips 2000 Series 4.2L is dead easy to use, fewer presets, smaller footprint, your dad won't be battling a wi-fi setup screen. The coating isn't ceramic but it's a well-tested unit from a reliable brand. [top7kitchen.au](http://top7kitchen.au) has a rundown of the current top air fryers with current pricing if it helps narrow it down.
I am happy with Philips 2000 series.
Very happy with my Philips 2000 series airfryer. Easy to use, easy to clean, doesn't take up much space in storage. A single basket is enough for what I need it to do. The complete machine feels very sturdy. Friends of mine have a Ninja. No complaints there either.
I think the best would be a single basket. Philips is easy to operate and easy to maintain. the buttons include various cooking options eg chicken, toast, grill. Go for Philips Series 2000 or Series 3000 Series 7.2L
I’d highly recommend going with Philips for airfryers. They have a brand history and their parts are easily available if required any replacement. One best thing about this bran dis the maintenance and durability. I've had mine for over 8 years. If you want to cook two different things at the same time, the dual stacked models are a great option - they save space since the drawers are built vertically instead of side by side. If you only need a single basket, the Philips 3000 Series (7.2L) is a solid choice, or you can also look at the Philips 2000 Series for a more budget-friendly option.
