What owners love
  • Stops door from opening even if lock is picked or kicked
  • Easy to install with just a screwdriver, takes maybe ten minutes
  • Aluminum doesn't rust and looks decent in satin nickel finish
What owners regret
  • Doesn't work on doors that open outward or have unusual frames
  • Screw holes sometimes strip out after a year or two of use
  • Needs really solid door frame or it won't actually prevent break-ins
