I created this product because it solved a personal need, as my infants were emptying out my cabinets, constantly making messes and sometimes handling dangerous items.
It worked well for me in my house so I took the plunge and created my own version.
However, others may have a different experience than me and others may use the locks different than I expected and find some issues that I haven't thought of.
For example, someone pm'ed me that their older kid can still get into the cabinet if they yank it very hard. Honestly that wasn't the intended use, it's aimed at protecting cabinets and closets from curious infants/toddlers that may hurt themselves or break something. And even a screw in lock would not be 100% protective from an older, determined kid. And of corse, the magnetic key will have to be hidden well from a smarter kid.
So it's good that it gets pointed out over here so no one has any false expectations.
I don't mind if someone constructively criticizes the locks though I would like for anyone criticizing to point out if they feel that they wasted $5 or not. Some people reading the criticism may think that the poster hates the product and regrets purchasing while the criticizers' intent may be just to help me improve a product that they love.
