When it came to babyproofing our kitchen, we got two of these locks, fitted them according to the instructions on our double oven and within days they were off again and being sent back to Amazon.
The instructions were followed to the letter, the oven was cleaned first and they were left for the recommended time but they just didn't stick very well. We would have got away with it and managed to keep them on as long as we opened them very, very carefully every time we wanted to use the oven. However if I could teach my 13 month old to be very careful when he's trying to get into the oven I could probably teach him that he shouldn't be going into the oven in the first place.
I am returning these for a refund as I don't think they are fit for the purpose for which they've been sold.
A heat resistant lock, easily fits to a multitude of kitchen appliances and cupboards to prevent access by children.
