We have one of those dual draw Ninjas, it was about £200ish

Quite big and bulky, but it's absolutely changed the game. Cooking times cut in half, energy usage in half....but everything tastes miles better.

We haven't used our oven in 8months as the airfryer has just dominated.

Wonderful devices. Highly recommended

It does taste better though, Mike, partly because you're using little to no oil/fat to cook with.  All I use is a spray bottle, which I top up with Avocado oil, and if necessary give whatever I'm cooking a little spritz before putting it in the basket.  Same with roast potatoes, instead of putting them in a panful of oil they get spritzed with oil, rolled in a mix of salt, pepper, (and sometimes paprika, garlic powder and onion powder too), and then go straight in the fryer.

Same idea behind my Cuisinart griddle/grill. It's amazing, the amount of unnecessary fat that drains off of stuff like sausages, burgers, chops, steak, bacon, etc., not that that will bother you. It's a step up from the George Forman grill I used to have, and they're pretty good too.

A lot of my kitchen gadgets are as much about healthier cooking as they are about making cooking for one less expensive r . 

I believe you mean "betterer". 

Or Mo Better Blues as Spike would say.

You need it to be easy to clean. That means you need to be able to dunk the drawer and basket and wipe clean the inside without difficulty.

I'd like to try one but every one I look at is out of stock

Don't overlook a halogen cooker. I have been using one for years now, with the oven now only getting used on very rare occasion.

You can - an air fryer is really a hot air blower. Whether the food cooks or burns is down to your temp and time settings.

If you look back over the page, Stan, you'll see I've just ordered one, so another positive reaction to them is great to hear.
