Lifesaver
If you read any review please read mine. This thing is a literal LIFESAVER. NO DRILLING. NO CRAZY INSTALLATION OR APP NEEDED. IT DOESN'T REQUIRE YOU TO BE 8' TALL AND IT'S LITERALLY CHILD PROOF BECAUSE THEY CAN'T REACH IT!! AAAAND IT WON'T LOCK YOU OR THE CHILD OUT. Only issue that came up had a ridiculously quick and easy fix. The arm needs to catch on your door frame and mine wasn't so I literally stole a  block from our Jenga game and screwed it to the frame so the arm would have something to catch on. Done. If this thing cost $100 I'd still tell you to get it.
