I was using a cutting board with a good blade contact, but even with the large size, the depth was narrow, so I bought this one, which also seemed to have a good blade contact. As a result, I find this size and shape very easy to use. The depth means I can move the cut food to the edge, and even when I cut large vegetables like cabbage, there is less mess. The blade is gentle and doesn't make that annoying clicking sound, and it can be stored in the same way as a square cutting board that isn't perfectly round. The blade is easy to damage, but the ease of use is better, so I'll probably buy this again when I next need to replace it.
