Product review (2 stars): Knobs okay, but adapters way too small
The knobs themselves appear to be sturdy and would probably work IF it weren't for the ridiculously small D-shaped openings in all of the adapters. One is so small that I promise you it could be used on a Barbie doll stove. There are four sizes of adapters included in the package but the largest one is approximately 3/16" and the smallest accommodates a toothpick. Maybe newer oven models have thinner stems, but for my old Magic Chef, these just don't work.
