Look on Amazon warehouse/resale - I got my Instant Pot (Versazone Dual Black Air Fryer - Large 8.5L) for £66 when the full price was £109. It was allegedly scratched but arrived in perfect condition. I had similar luck with a fancy bin, so check a few of the big brand listings to see if there are any ‘used’ offers.
One piece of warning about the Ninja dual baskets is that I've read many times that when you run both baskets it takes longer to cook. I have the Instant Dual Vortex dual-basket air fryer, it does not really take any longer to cook when you're running both baskets (maybe 1 minute at most) and you can run it with just one basket in there.
We have an Instant brand dual rack. The first one purchased Nov 2020 went out on us after a year or two and they replaced it. Still using the replacement a few times a week and it’s been fine. Just to throw another brand into the mix. (I’m not a bot or an instant shill just fyi)(or is that exactly what a bot would say?!? 🤖)
Kettle: Xiaomi We've had ours for 2 years, used everyday. No issues. Airfryer: Instantpot Vortex Used regularly for months now, works great. I like the oven style and tray vs basket style because easier to clean. I just pop the trays in a dishwasher along with the dishes. It also automatically preheats and dings to remind you the preheating is done.
Philips, Instant Pot/Vortex, and Cosori are all better than Ninja. Ninja has bad non-stack and low power.
I have the instant pot I was happy with its performance so I bought instant air vortex which is good as well. You can consider this as well. But I'll suggest you to purchase one with a glass basket instead of aluminium-ceramic
Hey, I've been using instant air vortex since 2023. It's absolutely fine working machine. Its given me no trouble at all. This one is a 4 litre. And since February 2025 i am almost using this everyday to cook chicken https://preview.redd.it/k6hcxflqqb1h1.jpeg?width=3000&format=pjpg&auto=webp&s=4dc6f8a511571bb5d45b28a2343ed8597a8a952a
