New GE switches: anyone have hands on using their associations capability?

Hello,

From discussion here it seems that the new GE switches have the capability to do wireless control of other devices through zwave association.

Has anyone had hands on with this?

How is the performance?

While linear has announced zwave plus versions of their switches I do not see them available for sale yet.

And previous versions of linear switches use pigtails for connections, I prefer the GE switches connection method.

The performance of zwave association control by linear aux switches are instant so I would want to the GE switch behavior to be as performant.

Are there any other zwave plus switches that have zwave association control that are recommended?
