Query: Cheap but poor quality...

I agree with some earlier reviews: These boards have uneven thicknesses, and the cutting surface is not flat. This means the boards can wobble on the countertop. Farberware may be inexpensive, but it's no bargain. Spend the extra dollars on a KitchenAid cutting board, which is thick, perfectly flat, and has non-skid rubber grips. If you're on a budget, Ikea cutting boards are even cheaper than Farberware but still better.
