(This review was collected as part of a promotion.) I received this product as a #voxbox #sample.  Not only is it sleek and classy in the matte black the installation was very easy.  I installed on a basement entry door that I was forever having to go get keys to open.  This makes entry easy without the need to get a key.  The matte black colour looks classy and elegant on the door but has such an ease of function.  I would highly recommend this lock to anyone!  Eliminate the use of keys!
