  • Rated 1 out of 5 by from NOT for glass stovetop. I went to the store and the clerk looked up a glass stovetop heat diffuser and ordered this for me. When it arrived at my house it clearly stated on the packaging NOT for glass stovetop use. It does NOT state that in the online description or product.

    Rated 5 out of 5 by from Great diffuser This diffuser works well with my induction cooktop. It broadens my options for cookware to use on the cooktop. I even cook directly on the diffuser. It is great for making buttered toast , grilled cheese sandwiches, and warming tortillas.

    Rated 5 out of 5 by from Did the job! Never used one of these but came across a pasta sauce recipe that required using one. Ordered the Nordic Ware hoping it would also help with my uneven electric stove burner and it did. It did a wonderful job distributing the heat evenly and keeping the sauce from sticking and burning at the bottom of the pot. Very happy with my purchase!

    Rated 1 out of 5 by from It warped after 2 weeks The Nordic heat diffuser worked well at first, but after 2 weeks started to dome. Now nothing sits flat on it. Would not recommend this product.

    Rated 5 out of 5 by from Every kitchen needs one. Many residential (non-professional) ranges and cooktops have difficult time regulating their low heat settings causing hot spots. This takes that out of the equation by disbursing the heat before it ever gets to your cookware. Need to warm butter without browning? This little disk will make all the difference.

    Rated 5 out of 5 by from Solved my problems We recently purchased a new home with a gas cooktop that is not professional line. The annoying challenges we faced were the inability of the smaller burners to maintain a simmer. The small burners were constantly causing burning and boil overs. The Nordic Ware Heat Diffuser solved our problems and eliminated an expensive replacement of the cooktop. This product works great and looks like a normal part of the cooktop when stored on the cooking grid. It fits multiple burners and is large enough to hold almost any size of sauce pan. Great product that I highly recommend to those who like to keep foods warm without burning or boiling over.

    Rated 5 out of 5 by from Great for stove with heat problems I ordered this heat diffuser for my mother. she has a stove that the burners even at the lowest setting are still too hot to cook certain things like rice. She called me and was thrilled that this product worked for her. She said the rice cooked perfectly after lowering to low setting using the product. for the first time nothing burned.

    Rated 1 out of 5 by from Over priced junk This is not up to the task and is well below WS standards. I returned mine to the store for the same reasons mentioned by the other reviewer. I purchased copper ones online and they perform fantastically. The copper ones are what WS should be selling. This actually deserves 0 stars, but...
