Product review (5 stars): Fits my Elmira-Heartland stove!
There are SEVEN FACTORS in whether knobs fit a stove:

1. Is the shaft the right shape?
This kit contains 9 knobs. Three of them (each with a different variation on "BAKE - BROIL - OFF"; one adds "TIMED BAKE" and the third also adds "CLEAN") fit on the common D-shaped shaft.

All 6 of the remaining knobs fit on the "two flat parallel surfaces" shaft. This is less common, but is what our stove has. These six include 4 burner knobs (marked, in clockwise order starting at the top: "OFF - LO - MED-LO - MED - MED-HI HI", with small straight "tick" marks between each of the markings (but not between OFF and LO and not between HI and OFF).

The other two parallel-shaft knobs are for ovens. One oven knob shows "OFF - BROIL - 500 - 450 - 350 - 250 - 150", with additional tick marks between the numbers, (1 or 3 marks each; each mark represents 25 degrees, as appropriate to the number of degrees between the numbers), which is right for our stove. The second oven knob has "OFF - CLEAN - HI BROIL - 500 - 450 - 350 - 250 - 150".

2. Is the writing in the correct orientation?

Some stove knobs have "OFF" on the bottom; others have it on the top. That means that, if you put on the wrong knob, the word "OFF" will be upside down. These knobs all have "OFF" on the top.

3. Is the writing in the correct order?

With "OFF" at the top, "LO" is always next to it - but on some stoves "LO" should be to the right of "OFF" and on others it should be to the left. These knobs all have "LO" to the right (clockwise of) "OFF".

4. Are the flat sides of the shaft holes on the correct side?

Stove knob shafts are positioned so that the flat surface(s) face a particular direction. The D-shaped shafts for this set should have the flat side on the right-hand side of the shaft. (Otherwise, the knobs won't have "OFF" on the top.) The parallel-flat-sides shafts for this set face up and down. (I bought a different set that was perfect in every way - except that the flat sides faced side-to-side.)

5. Are the knobs the right size and shape?

These knobs are the traditional shape with a wide, flat flange around the outside with the writing on it, and a central "handle" rising above the center of the knob. Viewed from the side, they look vaguely like a stetson hat with a flat brim. This is what you expect of an oven knob. (Our stove's original knobs were a different, cylindrical shape, looking vaguely like a hockey puck.

These knobs measure 2 5/16" in diameter across the flat flange. The "handle" portion of the knob measures 1 9/16". (Our stove's original knobs were just 2" in diameter and had no "handle" portion. But these fit and look fine anyway.)

Some knobs, seen from the side, have a curved outline. These have a straight outline. That is, the "crown" of the "stetson hat," seen from the side of the "wearer's head" goes straight up the front and back and straight across the top. Some other knobs look more like "bowler hats", with a rounded conture at the "front" and "back" of the "wearer's head."

Seen from the "front" of the "wearer's head", these have a curved slope at the bottom of the "crown".

6. Are the oven knobs adjustable to match a slight offset in the shaft or to match the oven temperature?

The two parallel-shaft oven knobs on this set have an unusual feature: there are two hidden screws that allow you to rotate the outer dial aoubt 10 degrees either to the right or the left. I guess this is to allow you to correct for either a shaft that is slightly rotated or to match the degree settings to the actual oven temperature. If you need this feature, it's a godsend. I wish the burner knobs had this feature, too, because one of my shafts is set in the stove with the parallel sides about 5 degrees to the left of vertical. I'll have to loosen, adjust, and re-tighten the control; adjusting the knob would be easier!)

7. Does the color and surface texture match?

These are a dark gray ("charcoal gray"?) and only slightly shiny. That is, they have a "satin" sheen or nearly flat reflectivity, not a shiny surface. They don't feel or look cheap.

MY SPECIAL NEEDS

I bought these knobs in the hope that they would fit my old Elmira 6000 stove. (This is an electric stove made to look like an old-fashioned wood-burning kitchen stove. This was an original Elmira model, which was sold to Heartland - who has created newer versions of it.) These knobs aren't the same shape or size as the round cylindrical knobs on the Elmira, but they fit and look fine. My model has a griddle, so I had to buy two of these sets to get a total of 5 burner controls and the one usable oven knob.

I spent hours searching the web for the knobs I needed. Since not all of the first five characteristics listed above are specified in product descriptions, I bought 5 sets of knobs ranging from the low price of this set to over $50 per set. Only two met the crucial characteristics 1-4 above. Only this set had both burner and oven knobs. For me, this set is a winner! And, as a special bonus, this is the least expensive set of all!
