Simple to use and saved my septic system from clogging!The coffee grounds go right through it so I put a napkin in it and that does the trick. It's nice a big though so that's great for cleaning out my French press and fits nicely in the corner of the sink. I would buy it again.This works perfectly in the corner of my undermount kitchen sink. Great place to leave my sponge, or strain things. The reason for four stars instead of five, is that it's painted black, and the black has already flaked off a bit on a corner.Loved the concept and really wanted this to work, but the suction does not hold and it kept popping off and dropping into the sink. Had to change it out for another product that sits on top of the sink.I found this impossible to insert the suction cup and to remove the basin from the suction cup. Do not buy this product.EhhDoes not work as intended. The placement of the hole is poorly placed and suction cup doesn't work nor does it suction well, didn't fit right in the corner of the sink. Great idea, poor execution. I returned the productDislike - did not stay suctioned to sink
