Actually really nice
I was a bit skeptical, my major concerns were that the grooves would be hard to clean, and the non-stick would eventually fade. Can confirm after about a month of usage (cooking curry, eggs, steaks, pasta, etc): very easy to clean, and the non-stick is flawless. The tall rim on the pans is super useful, and adds a lot of capacity. And however they made the curve on the fry pans makes it really easy to flip / toss food without using a spatula, so that's also a plus.
Only thing I would note: the pans have extremely high heat retention, so I've found that I need to cook at a slightly lower temperature than I normally would, so that is one adjustment you'll have to make.
My original plan was to use a stainless steel set for normal cooking, and this set when I need non-stick. However, now this is just the only set I use. Wasn't expecting it to work so well before I bought it.
