HI Maria, we love them! They’ve held up really well. Like literally still flawless and super easy to clean (even in this light color). The heat issue really isn’t a huge issue. It can handle some heat, you just can’t set a boiling pot down on it. The only thing to keep in mind is that since the seamless sink basin is pure white it does take a bit of effort to keep clean. But nothing a sponge and some soap can’t handle.
As for the boiling water, never had an issue and we strain boiling water all of the time.
Really hope this helps you make a decision!
Hi! I’m sorry I drop this comment here but I dont know how else I can contact you. I would like to know how your Hi-Macs countertop is doing after what I understand two years of installing them. Have you had any problems with stains or scratches or the heat issue? Since you have the seamless sink, have you had any trouble with the no boiling water thing?
