All of them are good. For their money, they are fine.
The only downside is that the food sticks and it's not easy to forget about it. Homemade bechamel sticks, dolmades and spinach rice stick. They are easy to clean, of course

The only flaw is their lids that do not fit well and are cheap in quality, compared to the pots.

I am very satisfied with this set/series. I have had the pots for almost 8 years and I use them daily. They have not warped, there has been absolutely no change in their shape, their bottoms, etc. The lids fit correctly. Yes, sometimes I would like to have 1-2 extra lids, but it's okay, I manage (for 5 pots it only has 3 lids). The handles made of bakelite are also very convenient.
The pots are very easy to clean, the bottom has never blackened externally.
Sometimes, if I don't pay attention, food may stick to the bottom, but it's also a matter of the housewife's attention. You can't just leave the food on the fire and hope that nothing will stick. I haven't had any tragic burning or sticking though. If something sticks lightly, with a more vigorous stirring with the spoon, it comes off and everything is fine.
The conclusion is that they have excellent value for money. It is a quality set, for everyday use, at a very good price. Now I see that the price has dropped, I bought it for around 100 euros in 2010.

The quality of them is very poor. The lids don't close properly. They are like children's toys. Unless mine are defective, which I don't think so. I wouldn't recommend wasting your money on them. It's better to go for another option.
