As easy and as fast as gas - we wouldn't go back.
5/5
Just as easy as gas but with so much more flexibility.
Some other reviewers have commented on the noise - yes it can buzz a little when you've got it up to the max but it's not really an issue - boils water faster than our plug-in kettle but can be cool to the touch a minute after you remove the pan (unlike electric).
Definitely the future of hob cooking.
