Hi, I love my Actifry. I agree that SW chips are much easier in it. Haven't tried spraying again half way through cooking - so will try that next time - good tip! I have tried doing stir-frys in it, just put a bag of shop bought stir-fry in and I thought it was really nice, also really nice if you cook some chicken & bacon cubes for about 10-15 mins before you add veg.
I've got the normal sized one, and I find that it does enough chips for two of us in one go - but that does give us a good half plate full each!!!
