Like the previous Kwikset electronic lock that I had installed, this is a fine product.  It has very nice fit and finish.  Installation was very simple.  I had no trouble at all.  Likewise, programming your own code is very simple also.  Having used this product for several weeks, I have not encountered any problems, and this product has performed as promised.  The electronic motor that opens the deadbolt operates slightly slower than the previous model, but is definitly not a deal breaker.  Some key features include backlit numbers and the ability to set the lock to your exisitng Kwikset keys, should you have any other Kwikset locks.  These locks are battery operated, and they are very easy to change out.
