Unfortunately, I was disappointed, very lightweight... the metal is thin, the lid bent immediately... of course, you might say, what did you expect for that price!

I bought it and visually it didn't seem like 9 liters to me. So I put water bottles inside and measured 6.5 liters. But even with math, calculating the volume:
Diameter: 26 cm
So radius: 13 cm
Height: 13.5 cm
Cylinder volume: V=3.14×13 (squared)×13.5 ⮕V=3.14×169×13.5⮕V≈7160 cm3.
So the volume of the pot (externally) is about 7.1 liters.
Unfortunately, I didn't do the calculations earlier but blindly trusted the manufacturer.
As a pot, I have no complaints for the money I paid. It is very light and just right for gas.

Four stars because: 1. Mine came with a small dent (nothing serious) and 2. It needs a bit of care when cleaning because the rim is very sharp (I got a small cut). Other than that, I would say it's good, food doesn't stick, not even creams that I made.

It arrived dented as you can see in the photo. A quality stainless steel does not dent easily. Observing the above, you realize that it is quite thin, which means thin layers of metal, so it is more vulnerable to impact. Okay for the price/quality. In general, if the stainless steel utensil is so cheap, expect low quality.

It is what it says: a fair offer for less than 25 euros, so five stars. It doesn't weigh 10 kilos, it doesn't have a five-layer bottom and frills (which no one expects at this price), BUT it cooks just fine, cleans easily, and hasn't deteriorated in the slightest despite almost daily use. I have it for induction cooking.

One of the best purchases I have made. Very high-quality construction. If I need a pot again, I will definitely get one from the same series and in different sizes.
