Yeah, that.
For anyone who hasn't used it yet....
It's like velcro except without all the annoying bits. It's much more of a "click in" feeling than a "squish on" feeling, and once it's on, pedals don't wiggle. Depending on exactly which version you get (there are various "strengths"), you might have to use a butter knife or prybar to get it to let go of pedals.
