Saftey 1st.

I bought one of these latches once my toddler son became interested in our oven door. I preheated the oven to 350, attached the latch & turned the oven off. I found heating up the oven helped with the latch attaching super well as it literally didn't want to come off when we no longer needed it. It kept my oven closed securely & kept my son safe.

I actually find that these work really well! Though my daughter is not very curious- as soon as she sees these on the cupboards, she doesn't really try to get in. They are easy to apply to awkward cupboard doors too!
