Lazy K Induction Cooktop Mat - Silicone Fiberglass Cook top Scratch Protector - for Magnetic Stove - Non slip Pads to Prevent Pots from Sliding during Cooking (7.8×7.8)

This is by far the best mat I have bought for my induction hob. It was expensive but since I have had to throw the others away because they have perished I hope this will last a lot longer. I shall be buying more very soon

Actually, the mat turned out much better than expected. (Bought the size Medium also.) Just the right thickness to be durable, but not too thick as to impede the induction cooktop sensors from detecting the pan (or impairing the efficiency of heating from as best as I can tell.) The mat itself is like a Silpat baking mat, thin, translucent grey-ish color with fiberglass woven in. The black edging and black radial "spokes" are actually silicone bumps, raised up from the surface of the mat. I wanted these to protect the cooktop from scratching and also to stabilize a pot so that it wouldn't turn/slide across the cooktop when stirring. The mat does that perfectly. Looks pretty good on the black glass cooktop as well. No feedback yet on long-term durability, surviving the dishwasher, etc.

No recomiendo este producto! Se quema y puede generar un serio daño a una parrilla de inducción y quizás hasta provocar un incendio. Afortunadamente en mi caso no pasó a mayores y el vendedor me reembolsó la compra.

I Iused it for the first time and decided to buy another one. It really protects my induction glass top and cooks fast.

Summary: expensive waste of money. Yes it will stop a pan from scratching the cooktop, but it also doubles the cooking time because the thickness of the mat weakens the magnetic field. Kind of defeats one of the primary benefits of induction. Wasted $90 on a set of four of these. +1 star for protecting the cooktop. The product does that job quite nicely and the pan doesn't slide around when stirring something. -4 stars for fact that it drastically cuts the heat output of an induction cooktop. It is too thick and the magnetic field is not as strong as when the pan is sitting directly on the cooktop. You can tell by the sound of the induction cooktop and the fact that when turning heat to Turbo mode, nothing much happens. Where I used to cook on a setting of 5-6, I now have to go to 9 or H. Where previously I couldn't use Turbo mode unless I was boiling water because everything would burn in less than 20-30 seconds, I have frequently used Turbo mode to cook the whole meal because it doesn't get hot enough to burn. I have timed this multiple times to make sure I was not imagining this. My test method: Turbo mode (highest setting on my induction range), Le Creuset teapot, 2 cups of 60 degree water heated to full boil as indicated by whistle going off. Cool teapot to room temperature and repeat. Average of 5 tests without mat in place was 1 min 18 secs. Average of 5 tests with mat in place was 2 min 47 secs. I have tested this with cast iron, an expensive Viking cookware set, and a nice blue steel Rosle pan that is my most magnetic and easily heated pan. All take double or longer time to achieve the same results as using no mat or a paper towel.

There's a good chance I will order two more mats for my daughter-in-law
