Never had an air fryer, not for us. We did have a halogen oven, used it a lot in preference to our aged cooker, but with our major down size came a down sized kitchen, everything has to work for its living. Checked the power consumption against the new oven, very little difference, in fact overall new oven seemed more economical so passed on the halogen cooker to family, who use it and love it. We do still use a Ramoska from our caravan days. Power use is negligible and it is earning it's keep - and space. Would probably replace it when it needs it. Too much choice out there now ?
