I tried it, with poor result. I'd be interested to hear if others have done better.

Here is a link that might be useful: My review on Amazon

I never thought I'd say this but...

I bought the Thermador 36" hybrid cooktop. Mainly because we have some old non-ferrous cookware, like a teapot, that we didn't want to part with. I should have went all induction and bought a hotplate.

My point is, don't bother with the Mauviel disk. You'd not only lose the benefit of speed and control over temperature, but you'd lose HUGE on efficiency.

We bought new cookware, Demeyere, and haven't looked back, it's that much better.

By the way, I bought a Mauviel fry pan and gave it to my in-laws. I didn't like it.

Thanks for the responses! But.. darn! We are moving to an induction cooktop and was hoping the disk would allow me to continue to use some of our old pieces. I guess not. :(

Trader_deb: didn't I see on another post that you're planning a 2 ring induction unit, then an induction wok unit, then another 2 ring induction unit? Why don't you just keep one of your 2 ring units to be non-induction?

mls99: We looked into that, but since so many people posted that they never looked back after switching to induction we didn't want to regret not going all-induction. My apprehension keeps me second-guessing our decision. Thanks for the suggestion though!

I have induction and am going back to gas. If I had the space, I'd go half and half with no regrets...

I like induction for boiling stuff and delicate stuff (great for candy) but I prefer gas for the rest of it. It's just more fun. :)

I just received this email from the folks at MetroKitchen from whom I purchased the induction disk I had to return. I am so impressed that they care this much about the quality of their products! So, a plug for MetroKitchen!

Happy Thanksgiving everyone !

here is the email:

Lee told me about your problems with the induction disk. We're very
sorry that it did not work for you. I am investigating it further
with the manufacturer because we want to make sure it works as we
promise on our site. We had been told that it makes most pans
induction-ready, but obviously that's not the case with yours.

Thanks for bringing the problem to our attention. We'll do our best
to help you try to use your current pans. For all of your extra
efforts, we'd like to offer you a 10% discount on a future purchase
at MetroKitchen.com. You can call us at 888-892-9911 with your
order and mention this code --xxxxxxxxx . Or you can order on
line and enter the same code in the "special instructions" box in the
shopping cart. (It's on the same page as where you enter your credit
card information.)

Again, we apologize for the inconvenience. We'll keep you posted on
what we learn from Mauviel about the disk.

Have a Happy Thanksgiving.

Great note from them! If you hear from them about the Mauviel disk, can you post it here? Thanks!
