The Nadiya Hussain 4 in 1 pan is excellent! It’s a good weight and instantly gives you the feel of a quality piece of cookware! It’s sturdy and comes with lots of added extras so that you have all the required lids for each job! As a wok it’s excellent! It has evenly distributed heating so that cooking is quick and easy and everything is thoroughly cooked. The glass lid is solid and has multiple uses as you can roast directly in the oven on its own as a pan, or as a lid on the main pan to casserole! 
It’s non stick and very easy to clean. The pan and lids stack together easily and don’t take up too much room! It’s an amazing set up and very versatile. I’ve found myself using it a lot more than I expected! It really isn’t just for stir fry’s!
