Well, I cannot speak for anyone but me, but I find it HUGE..it holds way more than I thought it would...As far as thin, Yes it is not thick any heavy..like my Le Creuset...it is very easy to pick up for me..My Le creuset is getting increasingly difficult to lift easly, another reason love the helper handle on this pan.
I have had mine for about 2 months, and have done everything but deep fry in it..steams like a dream, browns up meat and meatballs, sears, cooks low and slow on my induction burner..great for simmering, making candy....sure doesnt seem thin in any of these appllications..
Heats very evenly, no hotspots, and wipes clean, (but then so do my flip pans and other ceramics..) Like I would EVER only wipe something out and put it away!
No, I have never tried to brown onions without oil, and I probably never will..I like to caramelize onions with a dab of fat ...always do it that way...
Maybe it will fail to perform in the future, who knows, but up till now, I really like it, and it performs as advertised..didnt buy it from Chef Tony though, didnt know he advertised it..I bought mine on ITKWD from Eric Theiss,,
