"Agree with earlier review, the half bowl height must be higher than the main bowl as only half bowl height can be adjusted. Thought the pictures were confusing as shows both bowls having height adjustment on one shot but this is not the case. Did the job for me although the final wall outlet height also had to be adjusted with 2 extra 90 bends (ie built-in height adjustment on both bowls would have been more desirable)."
"This product is sold as fitting a 1 1/2 bowl sink, however it does not fit a 1 1/2 bowl sink that has near equal depth to both bowls it will only fit a sink where the 1/2 bowl is much shallower than the main bowl. The sink I was installing was a Blanco stainless steel 1 1/2 bowl sink"
