OK, maybe my bad for trying to install a sink over thanksgiving holiday when help lines are not available, but I did it. Sink quality is very good. Fairly easy to install but the retaining bolts that pull the sink down to the c'top are too long for a laminate c'top. Had to glue some spacers between the claw type retainer and the bottom of the countertop. I would not recommend this product if installing on laminate.
