I have had them for a month, bought on sale for €108, I have experience with Sitram and Tefal which I loved (I still have the Tefal but it is 10 lt so I have set it aside). They are easy to use and allow you to choose the size according to the amount of food. I have already used the small one several times, which is more than enough for the two of us.
It doesn't make noise, cooks quickly, without leaks, and is easy to use.
I hope everything goes well in the future.

I am coming back to say that the build quality is not what it could be.. I am removing two stars because the rubber has already started to wear out, so its replacement will be soon, something that did not happen with the Tefal I had.. Also, at times the lid does not close properly for an unclear reason.. and twice, without exceeding the quantity limit, it started to shoot water from the valve like a fountain..
In the end, I can't say that I am satisfied when with around €60 you can find a comparable Tefal set that is a guarantee..

So, I have had it for 4 years, I cook for the babies in the small one and for all of us in the large one, and everything is fine except for the sticking that has increased over time, so I bought a new rubber and a new valve..
It worked perfectly three measured times and then the same issues again..
Steam not coming out properly from the valve, liquids running from the lid, and generally a mess..
I am looking for their replacement and will probably use them as simple pots to keep my mind at ease..
