I use it. It's an outstanding cleaner for interior vinyl and plastic. Lasted a year (no kidding) on my Miata interior and about 6 months on tires I've used it on (but it's too matte on tires for my taste so I use other products for looks - Armor All, NXT Tech, 303, Vinylex). On the dash, it doesn't outgas and haze the windshield, doesn't attract dust, isn't shiny (the closest thing to flat that I know of). It also lasted a year on my Land Cruiser dash. It was able to restore a faded ashtray cover from a brown back to black in 2 applications and has stayed that way. It leaves a nice finish on leather but doesn't give the impression of "conditioning" like some leather lotions do. I like how it looks on leather. I'd say it's better than 303 on all counts except finish (personal preference, I like 303's slight sheen). Maybe I'll top it with 303 (?). Also had good luck with it on exterior plastic body trim. My cousin swears by it on the black trim around his Mini Cooper S. Also worked great for my Miata top.
