Have been in our house for 6months, the quantum quartz bench tops in the kitchen and bathrooms have been terrible from the start, bought the products they suggested but everything leaves marks,even water. Would certainly not recommend, I love the concrete look, but the stains and marks extremely disappointing.

So happy with my experience with Quantum Quartz! My Benchtops have been in for a couple of years, never had any issues. Still looking brand new : )
I chose Leggero which is so beautiful. My family and friends have all commented on how gorgeous my kitchen looks.
I would definitely recommend Quantum Quartz.

I'm a custom home builder/architectural designer who finally got around to building my own home. I wanted American made countertops however I found all faux marble options by Quantum's competitors to look fake with little to no small veining (this product is made in India). We ordered the Lazio in a matte finish. Clearly the finish is somewhat of "dull" finish as some of the reviews have stated but isn't that the case with all matte finish products? We had one scare from fallen pollen off of lilies placed on the countertops. I used a Mr. Clean eraser sponge and with a little work, good as new. Simple soap and water on a daily basis and this product looks great. We are extremely pleased and I will be installing in future projects.

Quantum Quartz Matt White is not suitable as a kitchen benchtop. This product was defective from the day it was installed. It is highly porous and marks as soon as you use it. It is not easy to clean and requires regular polishing with a special product. The customer service is the worst I have ever encountered, and they will not take responsibility for supplying a poor quality product. DO NOT BUY QUANTUM QUARTZ.

I have Quantum Quartz Mocha in my kitchen now for 8 years. I have 6 teenagers in my house. The benchtop still looks amazing. I have ensured my kids clean up after themselves, and use proper due care like I would any product and it has performed exactly how I expected.

My Quantum Quartz bench top has been in for one month now and it already has a chip in it. It was tapped by the bottom of a small pot and a chip flew off (I laughed when my husband said he had chipped it as I watched him do it, not believing such a small tap could break such a strong product....well I was wrong). This is not the quality or reliability that I was led to believe the product was. The prior bench top was Carrara marble (over 30 years old) and it was totally abused for the last 3 year and never ever chipped. The after service is rude, did not care that it chipped so easily and the cost of repair was hideous. Total thumbs down from me. Spend the few extra dollars and get another brand.

Like everyone else this product shows marks like you wouldn’t believe. Everything will stain it, mark it, dull it’s surface etc. It is incredibly easily to scratch even with a piece of foil when simply wrapping a sandwich. Jean zips will scratch and chip the edges and it even gets marked from water and oil splatter. It is not fit for the purpose it is sold. I am a keen cook and I don’t even cook anymore because the benchtop makes me so nervous. The company could be less interested. They just refer you to their cleaning product (which by the way also damages it). I wish I’d got caesarstone. Their product and aftercare are phenomenal.

We have a dark bench top, looks lovely but shows marks terribly, we have had to put wooden boards otherwise every cup or anything leaves a mark. We tried using the cream cleanser from this company and made it worst. In the pantry we have a light coloured Caesar stone which is so much better, doesn’t show any marks compared to the quartz. I don’t know if it’s just a dark colour but couldn’t recommend.

Had quantum quartz benchop (white) for about 2 months now. Overwhelming majority of marks, including water glass rings and even food scraps such as broccoli cannot be removed with water and some not even with the special quantum quartz surface spray intended for the purpose. I now have marks that even the quantum quartz cream cleaner won't move. Soooo disappointed. My understanding was this benchtop would look great and be easy to keep clean. I am a single woman who is conscious of cleaning spillages when they happen and thought this product would give many years of satisfaction. While it looks great it's functionality is disappointing and would love to hear from Quantum Quartz representative for suggestions.

I have carbon matte benchtops in 3 bathroom, powder room and laundry. I find it looks stained all the time. Very hard to keep clean. Wouldn't recommend.

I had Quantum Quartz Ultra White benchtops installed in my kitchen 6 months ago and I already have two small chips on the island bench. One was caused by a metal utensil being accidentally dropped from a height of about 10cm and the other appeared after no notable incident. I had noted the installer polishing with Gumption so I tried to polish the chips out myself, but I now have two dull patches surrounding the chips and it looks terrible. I have emailed WK to ask for a solution and received absolutely no response.
I have had Ceasarstone benchtops in other houses for years and never had any problem, despite much tougher treatment.
I would not use or recommend Quantum Quartz ever again.
