Query: Bad experience with stove knob covers.

The joints melt within a week. It just can't take the heat from the stove or from the oven that is underneath the stove. So the knob cover is hardly usable for a week and then you need to replace it. I am still looking for some reliable cover that would last more than a week and protect the stove knob from my 19 month old really active son.
