I am trying to upgrade my kitchen and add in some gadgets, but I really don't want to buy something that will end up being useless.

I am very interested in electric ovens and air fryers but I wonder if they work efficiently in Lagos.

I see so many brands, designs etc. and I am tempted. If you have one of them please share a review on this thread.
Please share your experience with using any brand.
Thank you.

Philips Air Friers have been wonderful.

Very much available & in use in Lagos/Nigeria
