Working well so far.  The instructions don't tell you, but the green lever is the one you use for urine-only.  I searched several online reviews to find that information to make sure I didn't misuse the toilet.  Also...many reviews complained/warned that the seat height from the floor was too short.  It was exactly the same as the toilet I replaced,  and we have never noticed a problem.  My partner and I are 5'4 - 5'6.
