Does what it says in the ad. And we are finding more uses for it. I bought an expensive new pan, under the search "induction hob pans" so thought the perfect pan I was looking at was suitable for induction hobs. So did the usual, unpack, dispose of packing and leave on shelf to use. Looked great! To be honest as it was so long between purchase and finding out It did not work on induction hobs, I bought this. Should just have taken pan to charity shop and bought a new one. This is great if you want to put something like a casserole dish on the hob to keep warm,, something we hadn't done before and are now thinking "thats great", and of course if you have a favourite saucepan that just does not work on your new hob, then this is great. And I am sure we will find other uses for it. But if non of your pans are suitable by a new set. And,before you buy an expensive pan make sure it is suited for induction hobs.
Does what it's meant to do very well.
