Title: Not designed for Porcelain Sinks--frustration at best!
Review: I purchased this "over the sink cutting board," for a porcelain kitchen double sink. What a disaster and if you don't have a sink with square edges, I recommend you keep your money in your pocket. Even with the wire tabs pulled out, on porcelain it looks great...just don't try to use it, for what it presumably was designed for. Those extendable handles are soft plastic coated, offering no grip to the edges of a porcelain sink. As a result any pressure applied while cutting or chopping will land everything in the bottom of the sink. Significant modification would be in order, but then I would patent it and start selling a product that works in every type and style of sink. Maybe even brag about it.
