The gen 2 Sesames have built-in extendable grippers instead of the detachable adapters of gen 1. Just pinch the sides in and pull to extend. Gen 2 Sesames also have improved motors for better strength and robustness, so they can handle more difficult-to-turn locks and are less likely to have mechanical issues. Hope that answers your question!
Currently we are also working on a new version of Sesame that will be able to handle locks that require turning one full revolution or more. It will also work with mortise locks and other locks that have the thumb turn and handle combined. We look forward to sharing more information with you when we can! - CANDY HOUSE
