Updated review: spitting and splintering
UPDATE: Originally, one of the boards arrived with a split in it, but I was still happy with them. After a few weeks of light use, hand washing and drying of the boards, I figured it was time to update this review and knock these down to 1 star. The boards do not hold up very well. Cut marks are deep, and they are starting to splinter. Another of the boards has also developed a split. Save your money and go with cutting boards from someone else. ORIGINAL REVIEW: I bought these cutting boards to cut down on microplastic exposure. This would be a 5 star review except that one of the boards arrived cracked (noticed while hand washing all of them before use). Despite the one cracked board, I did not return them, as I immediately started using the boards, was too busy to deal with it at the time, and the overall value was still there. These boards are great, the value is excellent since you get several of different sizes. I like that all sizes have the moat for juices, because sometimes you are cutting one or two chicken breasts or one steak and don’t want to have to grab a big board. I honestly am writing this review because I wouldn’t be surprised if the company sends me a replacement. If they do, I will update the review to reflect their customer service.

Very Well Made
The Hiware Bamboo Heavy Duty Chopping/Cutting Boards Set is a popular kitchen accessory that offers a practical and eco-friendly solution for chopping, cutting, and slicing various ingredients. Here is a review of the product: 1. Design and Construction: The set includes four extra-large cutting boards made from high-quality bamboo, which is known for its durability and natural resistance to water and bacteria. The boards are pre-oiled, which helps to enhance their lifespan and maintains their appearance. The thickness and sturdy construction make them suitable for heavy-duty use in both residential and commercial kitchens. 2. Size and Versatility: The extra-large size of these cutting boards provides ample space for cutting large quantities of meat, vegetables, fruits, and other ingredients. Additionally, the set includes different-sized boards, allowing you to choose the one that suits your specific needs. The boards can also double as serving platters due to their attractive design.

Good quality, if you keep them oiled last a long time
If you keep these oiled and do not soak them, these boards last a long time. Good variety of sizes, durable (I use the larger 2 daily), and again, if you keep them oiled, easy to wipe down and haven't shown a sign of splitting. Durable as well. Would buy again.
