I used to own these. Loved them, easy to store and nice to know you are keeping food items separated. Good for prepping multiple ingredients. Durable enough for “chopping” however, using serrated blades or excessive sawing motion will cause slices in the surface which will trap bacteria over time. Used them for nearly 3 years before I moved and tossed them because they had some of those slices. In for 2 for old times sake.
