I will give my impressions as well as a brief but complete seasoning guide to make it non-stick and ready for cooking. Also, contrary to what Skroutz says, this pan is made of carbon steel and NOT aluminum. Also, it is definitely not rust-resistant as claimed and requires a lot of attention in storage. It needs to be dry and in a dry place, otherwise it will rust in literally a few hours.
Impressions:
The 28cm pan is very high-quality and weighs 2 kilograms. This provides ample thermal mass, while not weighing as much as a comparable cast iron pan. Like any other pan of its type, it is simply excellent for searing and frying.
The handle is secured with rivets and has some kind of coating. I'm not sure about the material of the coating, but it can peel off (with a knife, not just by touching it with a towel) when exposed to very high heat. This makes the pan unsuitable for oven use, but I put it in anyway and honestly, it's fine. Even the manufacturer provides conflicting information regarding the oven issue in this model. So, in short, put it in the oven at your own risk.
Aesthetically, it is simple. Unlike other De Buyer models, it does not have flashy engraved logos apart from the handle. This doesn't matter to me, but it may matter to you.
If there is one thing that doesn't fully satisfy me, it would be the huge and very curved handle. It doesn't add much in terms of usability. It can make storage difficult and also obstructs placing the pan in the oven. It still fits, just can't have it centered.
So, I can confidently say that it is an excellent pan and its price, in my case €38, is perfect.
Seasoning:
I don't have a gas stove, so I used the oven method and it worked very well. I did 2 seasonings with a challenging first test. I made a simple omelette with just a few drops of oil. It didn't stick at all.
Step 1: Remove the factory coating. It's not a seasoning layer, but a light layer of oil that helps resist rust during transportation. It doesn't take much effort to remove it. Just run it under very hot water and scrub it. You can also use soap if you can't remove it with plain water.
Step 2: Preheat your oven a few degrees (~10%) above the smoke point of the oil you will use. I used corn oil with a smoke point of ~230°C and my oven was at 250°C. Only tasteless, highly processed oils with a high smoke point are suitable.
While the oven is preheating, heat the pan over medium heat (60%) for 6 minutes. Then, take 2 cotton cloths that you don't mind getting oily. Lightly oil one cloth with a few drops of oil. You need very little oil! Resist the urge to use more, as this could lead to failed seasoning. Then, spread the oil on all sides of the pan, including the bottom. You want a shiny, almost wet finish. If you have puddles, you're using too much oil! Then, wipe it evenly with the other cloth from all sides. You shouldn't collect much oil, we do this more to ensure the coating is even. It will appear almost dry, but the relatively smooth and shiny surface of the steel has all the oil it needs.
Step 3: Place it upside down in the oven on the middle rack for 1 hour.
After the hour is up, turn off the oven, open the door, and let it cool to room temperature. If possible, I would recommend leaving it for a few hours without doing anything.
Step 4+: Now it should be ready, but you can repeat steps 2-3 up to 4 or 5 times, but honestly, just cook something. I only did it twice and didn't bother putting it in the oven for a whole hour the second time, just half an hour. The result is a very non-stick pan.
