Says "SINK GENIE IS UPC RATED AND CERTIFIED BY IAPMO, TESTING AT A DRAIN RATE OF 13 GALLONS PER MINUTE." They don't show a UPC registration number as far as I can tell.
Looking at http://www.sink-genie.com/Video3.mp4 time 2:50says to me that this works similarly to a drum trap, in that the diameter is too big to allow siphoning.. I could see that the unscrewable sump could overcome the main objection to drum traps. Website http://www.sink-genie.com/ says "MEETS ASME A112.18.2-2015/CSA B125.2-15, UNIFORM PLUMBING CODE (UPC®)".
I have not seen one,but it looks like it could be particularly useful for some things, such as kitchen islands in areas where no AAVs are allowed.
