I tried the A-P MaxBright 2 Mirror Diagonal with my WO ZS110 refractor. The quality of manufacture was obvious. Fit without any wobble. Lens hold beyond reproach. With TV 32 mm Plossl images looked same as with WO Dialectric Coated diagonal. With Tak LE-ED 5mm images snapped into focus slightly better with the A-P MaxBright. The claimed scatter reduction appears to be accurate. I would recommend this diagonal without reservation.
