Purchased in March 2024 and used for nearly two years until recently moving. I generally pre-rinsed dishes before loading, and occasionally cleaned the interior, so I believe the inside is clean with no unusual odors or noticeable stains. Mounting bases for cable management are attached to the exterior of the main unit with double-sided tape in several places. The drain hose has been cut to fit the sink's position, so if it's not long enough, please purchase a new one. Also, the outlet of the drain hose has visible stains from being exposed to sink drainage. The nipple used for the dishwasher is also included. The primary side is G1/2 size.
