Review on Security Rail Childproof Guardian Rail Foot Operated Keep by Cody Stroop

I am absolutely devastated. We were about to install this thing and when we put one of the screws in it must have gotten too close to the glass and exploded and shattered our new sliding glass door. I have no words now. It had no real instructions, how was I supposed to know that was going to happen?! Now the $20 item I bought to keep my little one indoors poses a serious threat to her and will cost me hundreds if not thousands of dollars after repair costs. I'm just devastated.
