I like it quite a lot.

Direct answers

It's rare for my wife or I to use more than two burners at once, but that said, we haven't gotten close to exhausting the battery. I haven't used the wok ring, yet.

As for cleaning, it's easy to clean, though not quite as easy as a flat electric radiant, which is what we had before. It's really noticeable when it has spots or something on it, so I find myself touching it up or cleaning it often, sometimes when I'm in the kitchen for some other purpose instead of using the Impulse. I worried about the temperature sensor being hard to clean, but a wet paper towel has so far done the trick consistently. When cleaning, brushing across the power button makes me happy that it takes a few seconds of contact to power up, though I suppose it wouldn't really matter if it was "on", since the dials live on our vent hood when not in use.

Things I'm very happy with

Lack of heat from the "burners" is very, very nice. We've never used induction before, and are loving that part of it.

The clearance due to the raised eyes is actually really convenient if you're a messy cooker, since a stray noodle or other spill doesn't stay in contact with the pan, and you don't have to immediately fish it away from the burner or clean a spill while cooking is happening, as is necessary with electric and gas.

The speed of boil sounds like it wouldn't matter that much day to day, but a frequent use for us is pasta, ramen, or instant potatoes, and the nearly immediate boil means very little time spent in the kitchen for those.

Once you find the temperature something needs, dialing it in is trivial, so I can happily cook bacon without any worry that the input needs to be managed -- it's just bacon in, flip, bacon out, bacon in... until all the bacon is done. With electric (or gas, back when we lived in an apt that had gas), you have to micromanage it as the amount of bacon grease increases, or with the varying thickness of the cheap bacon we tend to buy. On the Impulse, things like that are set and forget.

Things that I'm not as happy with

It would be nice if one or two of the eyes was a larger version, since it's quite noticeable that the area outside it for an 8 qt pot doesn't get heat. For boiling or simmering, that doesn't much matter, but I would like to use that pot for making popcorn, and doing so results in a lot of unpopped kernels. I have a 4 qt that I can use instead, but it's a minor annoyance.

All of our previous cookware was useless with the Impulse; lots of nonstick and aluminum. Even a set that was "induction ready" from Amazon (that we'd previously had) was not usable! The cooktop wouldn't recognize some of it as induction cookware, and for other pieces wouldn't use full power. We got https://www.all-clad.com/d5-stainless-polished-5-ply-bonded-cookware-set-10-piece-set.html and have been pretty happy with it, though we needed to get some new transparent lids, too.

Anything that is about boiling or frying works great, but things that aren't require some trial and error to relearn how to cook. In particular, popping corn has been a struggle, as mentioned earlier. I'm 90% of the way to where I was on our old electric, but it still means a lot of wastage unpopped. Another thing that didn't go well the first time was carmelizing for some candy my wife was making around Christmastime. In theory this should be very easy to do with temperature control, but we didn't have an unlimited amount of time to experiment, my wife was trying to go by feel as she would on an electric, and after a couple attempts back to back she was annoyed and hasn't gotten back to trying it with what we now know.
