topcor- kitchen sink

My kitchen is about to be renovated and the contractor wants to use a Staron countertop and a Topcor sink. Does anyone have feedback on the quality/ durability of Topcor material (also an acrylic solid surface)? Staron is made by Samsung and has good feedback on the internet. However, Topcor is made in the PRC and I am concerned about its durability (based on previous experience with locally made solid surfaces...) We have the option of getting a Staron sink instead, but it is much bigger than we need (countertop space is so limited here as it is...) However, I'd rather go bigger than have a sink that gets stained with coffee, etc. after a few months. Also, the sink will be molded into the countertop, thus almost impossible to replace later. Any advice/ feedback would be great.
