We purchased the Emtek 5312 MODERN RECTANGULAR LOCKSET for our remodel based on what I thought to be numerous positive reviews and the modern design.
Unfortunately the external handle/lever has turned out to be a 'sloppy' engineering design as can be seen from the attached video clip. My requests for an explanation from Emtek's customer service dept. was "...All of our key in levers/knobs have play on the base of the style due to the design of the unit, not a flaw...".
The amount of play on the external handle set doesn't exist on European designed and manufactured locksets based on all my travels. Next time I will purchase the better quality which apparently only exist in the old school European built locksets.
