HÄLLVIKEN quartz composite experiences

I have had the Hällviken 1 1/2 sink for 5 months. It looks great, nicely flush with the countertop.

Now the negative: When pouring out the pasta water, the sink cracked completely, almost all the way around starting from the drain.
First reaction from Ikea: Your own fault.

I believe that something like this should be withstandable by any kitchen sink. I am curious about the next response from IKEA.

Your own fault for pouring hot water into a sink?

You pour the hot noodle water down from the balcony. What a crazy idea to pour it into the sink.

So, she has to put up with that!

Hey,

please tell me how it continued.
A blunt statement like "serves you right" cannot be left as is for a sink costing 211 euros when pouring out hot water!

It says in the catalog: "A robust quartz composite sink that is stain, mold, heat resistant, scratch-resistant"

I installed the same sink this weekend and just find it great, I will also take good care of it, but if they seem to be that sensitive

Hello, I'm digging up this topic because I'm currently assembling my Metod kitchen with a Hällviken sink and Liliviken drain set. I noticed that there is no button to open and close the drain plug. Ikea also doesn't have retrofit sets (excenter mechanism) for this. Before I finish connecting everything, I wanted to ask here how the opening and closing of the plug works with the Hällviken sink. Can someone tell me something about this?
Thank you very much!
