It does what it's meant to do. It keeps a gun or Taser easily accessible while denying access to kids. This safe is big enough for a full size Smith and Wesson M&P a gun light attached. It's foam lined to protect the gun. The batteries last at least a year (I change them once a year to be safe). The biometrics work well for me and my wife. It is able to be lag screwed into a wood shelf. 

My only criticism is that I would prefer to have a vertical mounting position so it can be be secured to the studs in a wall without the gun falling out when the safe is opened.
