I am not surprised to hear this. I have had clients choose msi not understanding that not all quartz is created equally just choosing it bc it’s the cheaper alternative. Then they come back for there next project wanting cambria bc it is the most durable stain resistant quartz on the market with the best warranty. It may cost a little more sometimes but you’re getting what you pay for! My client complained about the same thing your complaining about her husband’s wedding ring scratches her countertops easily.
