A good dishwasher-safe alternative to my bamboo boards

These are great cutting boards for everyday cooking. They are rigid boards and have a decent sized surface for cutting, although not overly big so they are easy to store. The silicone pads on the corners keep them from moving during use, although I have found that the pads do not make both sides of the board non-slip, though if you adjust the pads you can choose which side you want to be non-slip. I like these being in two colors, keeps things more hygienic as I always use the black one for meat and fish and the green one for vegetables. So far, there are no cutting marks on them, although time will tell how long this stands up to use (I've only had them for a month). I normally use a bamboo chopping board as they are more hygienic than plastic (was very surprised when I found that out) but bamboo boards aren't dishwasher safe and I needed some for when I need to cook quickly and want to reduce the amount of washing up.
