So glad I bought them
Much better than the Fritschi system. The light weight alone is justification for the purchase. On top of that, these have much better torsional rigidity making turns actually an option.
Clicking in and out is easy and adjusting the heel for variable pitches is easier with practice.
They're rock solid, despite the very limited connection to the boot. I've skied them on spring bumps with no release and taken at least one good fall without a release. Just in case, they do come with a leash that's easy to install. It's a little short, but good enough.
Pair them with a good ski and enjoy lightweight, bomber ski control.
