Product review (5 stars): plastic knobs, but great quality, perfect
We had 2 of these that broke. Saving time and money of having to venture out to a store, we purchase these here on Amazon for a much better price. They fit perfect. Easy to install with very little effort. They are plastic, so you many encounter them breaking later on. It's just normal wear and tare. They don't make metal ones. At least not that we have found. These do the job, making us happy :)
