when you say it's dry.. very obvious

1) it's either you skip the defrost step
2) you did not spray some oil in it

i did those mistakes when i first started using air fryer when phillips launch their first model back in 2012/2013? since then i have been using air fryer only. now CUBIE XL though.

PS: i don't goreng food at home too.. uses too much oil - waste too much oil - and my apartment will stink as a result.

that's only a problem when you don't cook often! hahahaha 
if you use them daily like i do.. i don't even need to follow their manual or guide anymore.
but how you keep your oil/left over oil? don't tell me you pour all of it into the basin every time you deep fry something ah.

storing left over oil is something from the past unless you still do them but definitely not for me.
