I actually haven't heard of it before either. Just did a little googling and it seems super interesting. Would also love to hear if people have used it!

The Neolith is great for wall cladding applications since it comes in a thinner slab. We have samples here in our showroom available to be viewed.

Have you installed any as countertops? That is what I am looking at using it for.

An ideabook on Houzz (see link below) mentions a porcelain product not yet [readily?] available in the US. I was very interested, but couldn't find anything when I first looked. You seem to have found the product or something very similar. This material seems to be available in colors, large slabs and tiles, and at an affordable price point! If you like simple edges maybe it's worth buying a piece for testing. I might just do that.

See this ideabook, and the ensuing discussion, too:

We have not yet installed in a countertop application. I would recommend ordering a sample and testing it out. With this material a mitered edge profile is recommended.
