    NinjaDouble stack XL2 basket air fryer

    My wife and I have wanted an Air fryer for some time now we finally settled on the Ninja one reason is we wanted to be able to cook 2 things at once and the double stack is a counter top space saver simple ease of use and being able to cook 2 different things at the same time is utterly the best idea I've seen in a while either basket produces a well cooked meal at the same time and one thing I'm very happy about is French Fries that are perfectly cooked but with no unhealthy grease I give this air fryer a 5 star review get yours today you won't be disappointed.

    Best on the market; hands down.

    Great air fryer. Ninja is the standard and you really can’t go wrong with this, especially if it’s on sale. Cook amazingly, food is always tender, fully cooked to perfection. The stacking helps with counter space as well.

    Great air fryer with many settings and accessories

    Excellent size as it’s not bulky and works great! It saves some counter space and fits nice and snug. The quality of the air fryer is most certainly an upgrade from our previous one by dash:). I thought the price point was a little high, but if you think about all the settings it has and for all it does, the additional thermometer included and basket racks, it’s a stand alone replacement for an oven! I love to make dehydrated fruit snacks as well and this machine does that too!
