Buy the GlideLok. If you think you need it, just do it. You won’t regret it. We have lever handles and using the stupid flathead style bedroom keys a hundred times a day was driving us crazy.
The baby-proof stuff for levers had the potential for locking an adult in if the kids so decided, so those were only useful for the pantry. Frankly, if your kids are as smart as most of the ones I know, even if you have knobs and were going to do the cover they make for those, save your money.
Just install these where they are snug as a bug in a rug and even when they pull the dresser over to try and figure this thing out ... they physically cannot.
