I bought this stir fry pan to replace an old Teflon one after I read about health issues Teflon may pose. I didn't believe anything could be as good at not sticking, but so far I am delighted with this.  The pan itself is light but very stable on the gas hob, even when empty, which I wasn't expecting, as the handle offers a solid grip experience.  Cooking-wise, if anything, I'd say that the pan doesn't get quite as hot, so the food takes a little longer to cook, but for me, that's good as it's more controllable.  Cleaning my Eco pan is extremely simple as there's no burnt on food and no aftercare required, unlike my previous cast iron and steel woks.  Overall, it out-performs all my other woks and stir fry pans and there was a bonus tree planted too!
