Instruct: Classify Amazon reviews into positive or negative sentiment
Query: first time I've ever been compelled to write a negative review online

The concept would be great if the lock actually stuck to the door. I cleaned the door as directed and it popped off the closet the first time the other door slid into it. I reapplied with the second piece of adhesive in the package and it had popped off again within hours. There is no way this will hold up to a determined toddler. It will be returned (especially since I paid $8 for two flimsy pieces of plastic and weak adhesive that I'm sure only cost pennies to make).
