Top positive review
Very simple and effective lock, if you properly clean the surface

Some reviewers have complained that the tape doesn't adhere to their oven, but I'm convinced it's because they just didn't clean the surface properly first.
That part of an oven almost never gets cleaned, and I was shocked by how thick and stubborn the layer of grease was. It took several minutes of scrubbing with harsh chemicals to get down to a clean surface (409 did the trick). After that, I stuck this on and it seems extremely well bonded. Our 2-year-old has thrown his whole body weight against it, flexing the whole face of the oven without any movement from the lock.
It's also very simple to operate, even with oven mitts on, since you just have to move the whole exposed portion to the side and flip it up.
