Product review (5 stars): Great Reflector Bowls
By far one of the best items for the price I have ever purchased on Amazon. These lines are a heavy gauge metal and though I'm not sure exactly what it is it's at least twice that of the lines that came with the stove. I purchased the GE/Hotpoint porcelain ones.

Speaking of those that came with the stove... they were a polished aluminum that stained easily and were very difficult to clean. The last straw with my original inferior liners was when we used a large pressure cooker on the stove and the liners burned to the point that they couldn't be cleaned... they were in shades of black & blue on both sides. Since they were silver in color the stove top then looked terrible and the burning would have come from the use of any large or oversized pot. The stove was not a cheapie and I'd expect the liners to hold up better but I was wrong and since the liners had to be replaced... or covered in foil for eternity... I opted to try these and I'm glad I did. These also sit in place and do not move around!

These are not only black but they are also enameled and much easier to clean. Since the stove is white with a black door and control panel these look great and enhance the look of the stove. Since they're black every speck of crud that falls isn't very noticeable and I can stop being as anal retentive about cleaning. The only drawback to them is that they transfer the heat and get very hot... much more than the original ones... and that heat will transfer to the range top. I wouldn't call them "Reflector Bowls" because they don't reflect as much heat as they absorb.

Lastly, these lines also only accommodate one set of alignment tabs so if your stove elements require three of those alignment slits in the liner then these won't work... as another reviewer point out. However, the description does state they have a locking notch and not three locking notches. If you don't have a GE or Hotpoint they perhaps the Universal is what you need.
