that why I like instant brand dual airfryer. you can use it as a single or dual . got plenty of surface area as a single to get stuff crispy
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?!? 🤖)
Some personal feedback on this as I spent the last week picking an air fryer. Size of the fryer was a big factor in our search. First I bought the Ninja Pro XL 6 in 1. I liked that it would get to 450 degrees. We ended up returning it because it was so loud it sounded like a plane taking off. Second we got the Instant Pot, due to the positive online and Americas Test Kitchen reviews from a few years ago. We got the updated version with the window. That one got returned because one, it smelled absolutely awful when heated. Second, the bottom plate would pop up and sit at an angle as soon as it started to warm up. This is a safety issue because it would fly out when trying to dump out hot food. After looking back at the "positive" reviews, I realized they are almost all incentivized. Third and final one we got is the Ninja Foodi 8qt two basket fryer. So far so good. It's still kind of noisy, but it's tolerable. The dual basket is a nice option. Also even though it's dual, the dimensions are still surprisingly compact. It's slightly wider than a single basket model, but it wasn't any deeper. We also considered a Midea because Sam's has some, but they are huge.
I purchased the same Vortex Plus with front window from a thrift store with the "Close Basket" error. The only solution for me was to open the unit and replace the micro switch. When you close the door, a cone shaped extension, visible on the top front center housing, gets pushed up to the micro switch. If the micro switch is faulty, you'll always get the "Close Basket" error. This used unit has been working for close to 2 years.
Instant Vortex Plus. I got it for ₹8100. https://amzn.in/d/0fRkEJ1V
