Product review (2 stars): So far, the cooktop is great. EvVive? Not.
Avoid evVive.

The cooktop we received was not new. The Energy Guide label had been removed. It didn't include the owner's packet. It had stuff adhering to the cooktop. It didn't include the foam seal for around the rim. Nothing was mint, not the item, not the packaging.

The way it works with Evvive is that you send an email, and 24 hrs later, you get a response. After a couple of days, evVive agreed to a full refund and to pay shipping, although they insisted that the items was new (Excuse me, we can tell factory direct from fiddled.)

First they said they'd send a Fedex shipping label. It never showed up. Then they said the Fedex person would have it.  They never said when the Fedex person would show up and didn't provide me enough information to work with Fedex. Then I insisted on a Fedex label so that I could control the pick-up. Oh no, if I get a label, I have to deliver it to the nearest Fedex Ground. Whatever. The label isn't sent. Finally I get a phone number. I call. I get the label, schlep the heavy thing to a terminal (miles from my house).  Now lets hope they refund my money.

In the meantime, I order the exact same unit from Home Depot. I pay a bit more, but the cooktop arrives in mint condition. Spotless.

I will never buy from evVive again. Any money I saved was lost in wasted time.
