Here is a comparison between different Slim Series models

SF: Normal Slim series in Matte Black

SFS: Normal Slim series in Silver

EF: This lock has different styling and It is a more sophisticated lock in several small but useful ways:

• Less easy to be accidentally interfered with from the inside as the metal battery cover is screwed down (good for shared entrance halls)

• Added Privacy Button allowing you restrict electronic access to just opening by the master/owner account on the app (all other means temporarily suspended at the flick of a switch).

• A wider range of downward movement for the handle compared to other locks on the Slim series

DFF: Double-sided door lock. It has the same styling as the EF model but with:

• A fingerprint sensor on the inside as well as the outside

• Separate locking modules for inside and outside (good for situations where for safety reasons you need to restrict access going out)

SS Premium Slim Series: This is our newest and most advanced smart lock, designed by us from the ground up as an evolved product to meet the needs of more prestige settings:

• Sculpted design to fit in with contemporary styling trends

• More convenient positioning of the fingerprint sensor, exactly where you thumb naturally sits on the handle

• Safety Button, an additional feature to combat manipulated entry through a letterbox.
