Glad I bought this Schlage lock. I replaced another lock of inferior quality, which the mechanism began to stick, making it difficult to unlock the door. This Schlage has smoothly working mechanics. It was easy to install, even switched the handle for left hand open. Love this lock!   And being Schlage I was able to get it keyed to match my other doors (also Schlage).  Definitely worth the money to get a high quality product!
