The gaskets seem visually and qualitatively fine, but despite claiming to be compatible with my Mokka express 2-cup, they did not fit very well and the coffee pot failed to make coffee, it was leaking halfway.

It does its job, I would prefer Bialetti to also deal with silicone handles that are more durable, because if you leave them on high heat they can burn faster and smell strange, while silicone handles don't suffer any damage.

P.S. My wife leaves the coffee maker on a lit burner (it works with a timer) longer than necessary and doesn't use her brain.. what can I do! :p

We don't need to talk about the quality of Bialetti. So if you want to drink good coffee, you have to regularly change the rubber seals.
