I just purchased this 2 in1 Sink Strainer & Stopper. I bought it because it was an OXO. I've always been happy with their products. This is a simple gadget that shouldn't have given me so much trouble. It does NOT fit my standard sink. The only way I could get a suction on it to hold water in my sink was to invert the removable cup and I'm not sure that's how this is supposed to work. Correct me if I'm wrong. I'm going to need to return this for a refund and find something simpler.
