I've used a different version of the MKS pedals with these quick release of the entire pedals. The entire pedal can be removed for rinko or in my case make the bicycle less appealing to "ride away thieves".
I didn't like whatever cleat system that was being used and had a hard time clipping in quickly.
I've since got over my neurosis and back to mtb style SPD system. Much easier, faster, and consistent engagement. I wish these MKS pedals were around when I was in the market.
