Product review (5 stars): Works on Whirlpool, can use blank without numbers if you prefer.
After researching on Amazon, I needed these right away (moved into a house with the knobs missing, I HAVE to cook!) so I bought them at Home Depot.  They work perfectly on my older Whirlpool range.  Nobody seems to mention this, but I needed blank knobs (NO numbers) as my stove already has numbers.  The come blank, with two sets of setting numbers for you to attach if you want.  Perfect for me!  For those who wonder, the do work on the type of stove where you have to push in the knob to turn it.
