Query: These locks are the best

The Kidco magnetic locks are the best. Really, any of the babyproofing products by Kidco are far superior to other brands. These locks are incredibly easy to install, I did our whole kitchen (about 12 cabinets) in about 30 minutes. They don't require you to drill into the cabinet, and they also don't show on the outside. They also have a deactivation mechanism if you are working in the kitchen and going in and out of the cabinets a lot.We ended up purchasing some extra magnetic keys (you can find them in stores, not always available on Amazon.com) because we often misplace them, but you can put them on the fridge which seems to work well.
