Product review (5 stars): worked exactly as billed
installed a reverse osmosis filter system with a pre-existing garbage disposal. this attachment made installing the RO drain line a snap. no leaks, installed easily. i did need to buy some adjustable clamps to secure the tubing to the device (hardware store, cheap). the adapter is fairly sizable, and this lead to moving some of the tubing around to accommodate the size and avoid bends or kinks in the dishwasher drain line.
