looks a bit crap to me.
Maybe its normal.
We went with Corrian (or a knock off spanish version, actually), and its great. They gave us the “hole” for the sink as two chopping boards, but he said keep hold of one of them, and in the offchange you damage the worktop, they can core out a hole and use the cutting board as a repair patch. You wont be able to tell its been done, because it blends together so well.
You can see (or more, you cant see), where the deep 40mm face surface, has been bonded onto the thinner 10-20mm worktop, it is indeed totally seamless.
The sink is seamlessly bonded in too. Zero crease or notch to accumulate dirt.
Its noice.
Like this, but this is off the web.
