High-density polyethylene is one of our least favorite cutting board materials, but we appreciate that it's at least using recycled materials. As a plastic cutting board, it IS dishwasher-safe, but just know using the dishwasher has a tendency to warp most boards. The real problem for me is the texture, which makes it glide around the counter easier than any other board we tested.
Material actually just launched a new version with grippy feet to counteract this for $5 more, but regardless... I wouldn't recommend this board.
