Query: Great product, worth the installation

These tot locks are time consuming to install, but are well worth the effort! We have solid wood cabinets in our kitchen, and they work fine for us, so I am not sure what happened with the other reviewer.Our son never pinches his fingers in the cupboards and we have yet to lose the key. we just place it on top of the stove, and on our mirror in the bathrooms.tot locks have saved me a lot of clean-up and worry. I think they are wonderful
