There is nothing easy about this product! I spent 30 minutes trying to separate the two halves. I have watched more than a few U tube videos and they all act like there is no big deal about opening it. Good news. This product is really safe. Can't be opened. Bad news. Can't be opened. What the company needs is a user for dummies video that goes step by step on just opening the knob cover. No way I'm putting it on the door knob because then I'd never get it off. Guess I'm stuck with it because they aren't enough money to warrant shipping back. My 3 year old great granddaughter (who has now learned how to turn doorknobs) will just have to stay out of my room. Right.
