Best purchase in a long time

Held off getting an air fryer then finally went for it and I am so glad I did, this product is brilliant, I did a whole beef joint in it and it was perfect, love the sync facility so if you are cooking items on a different time and temp you can sync the drawers so they finish at the same time, would definitely recommend

Yes, I recommend this product.

Best time saving gadget

Bought as a gift for my son. I already have 1. Would recommend when you have little time to cook. And little space in your kitchen. Stacked is much better than side by side.
Cooks food crispy. While my conventional oven is warming up I can have cooked and finished in my Ninja.

Yes, I recommend this product.

Great features

I absolutely love this air fryer! The two separate drawers are really convenient for cooking different foods at the same time, and the synchronization function makes everything finish together. It cooks consistently, gets food beautifully crispy, and is very easy to use. The size is perfect for cooking meals for two people without taking up too much space. Very happy with my purchase and would definitely recommend it

Yes, I recommend this product.

Good Air Fryer

I have only used the XL Airfyer once cooking fish and chips, the frozen chips came out nice and not too crispy as we, actually, took them out before the crispeddon’t like prefer cooking our own, we have only used a actifry before but unfortunately it gave up the ghost. I would give it five marks for the chips but we have not yet found a way to turn over the fish, so we ended up with crispy batter on the top but had a soft underneath. How do people turn the fish over? We tried twe spatulas then a wide flat metal but we never manage it. Yes really it did the job well but we are in our eighties so we hope someone will tell us. The silicon mit is not the answer. Where there’s a will there’s way. Honestly it seems a good air fryer and does not pour out as much heat and steam as we expected.Word of warning: remove the crisper at end of cooking as odd chips sneak through it.

Yes, I recommend this product.
