Problem solved these work perfect & I can hear him when he is trying to figure out how to get outside now

But it has worked great on all the other door knobs

Only works well with some style door knobs.

Easy to install and works perfect!

These work well to deter my 22 month old toddler from getting out of her room at night

Not too bad and it works

These work well for my two year old

They have worked really well for over a year for us

These work so good that I struggle to open the door

So I bought this and it has worked so well, my three year old can’t break it much to her chagrin

These are the best and have worked the best for my 4 year old son.

The door knob covers work great.

Great price and works!

Work great, easy enough to open for me and keeps my 2 yr old from getting out

These work super well but depending on your doorknob they can be SO hard to work

These work really well

The door knob covers worked great.

I love them and my 1 y/o hates them.

some of them are a pain and these r easy and work great
