I have had the 30" cooktop with the original configuration for a little over two years.
I really like this cooktop: rapid heat and can light it with a match during power failures.
I use a flat-bottomed wok (because I had it before I got gas) and it works fine. Can't comment on rounded woks and wok rings.

Some negatives (but OK by me):
Need to clean in the dishwasher (I'm a very messy cook), as opposed to cleaning an even surface.But it comes apart easily, and the drip plates are very easy to clean.
Handles that are soldered, as opposed to riveted/screwed, on pots may loosen during high heat cooking.
There is no lip where the cooktop frame meets the countertop. That means that debris could fall between the cooktop and the countertop. For me, that's not a big issue since my previous range with a lip still collected debris. At least I can use a toothpick to clean out the gap.
The simmer burner at the lowest setting is too hot to cook rice or dried beans, but I use a separate metal plate to cover the burner. That works fine. While the flame can be adjusted, I never bothered to do so.

HTH.

I also own this cooktop. I'm happy with it.

It is a pain to clean sometimes and you have to realign the ignitors. Also, the simmer is a little high so that may be an issue with soups. But, you can use induction for that.

I have a full size Chef King Griddle to use over the entire cooktop.

I did have an issue ordering. I had to wait more than four weeks longer than I should have to receive it. Production shut down and Bluestar wasn't good with communications. The screws stick out further than the cut out dimensions the factory provided to the granite fabricator. The screws were shaved though and everything worked out in the end.

Canishel and Sreedesq,
Thanks so much for your feedback. I am a neat nik but don't mind doing the cleaning. I like the fact that it can be lit with a match also. Sad to hear that the simmer burner is a little high. I will at least have the induction for simmering. What adjustment is there to the simmer burner?

Carnishel,
How is the wok cooking? I have flat and round bottomed woks and will continue to use both.

Sreedesq,
I may have to get a griddle. Everyone seems to love them. I have one with the Dacor now but don't use it except when I make bulgogi. How is it for pancakes? The one that came with the Dacor was very uneven with the heat.

The only thing I wish Bluestar would do on the cooktop is offer an option for colored knobs! I want yellow knobs for some unknown reason!!!

Re: burner adjustment
The instructions refer to air shutter and low flame adjustments. I don't know whether either adjustment affects the heat. I haven't been sufficiently interested to find out.
Bluestone customer service was very helpful during installation, so they may be able to tell you.

Re: wok cooking
I have two thin carbon steel flat bottomed woks. They heat up fast, and food gets that nice brown edge without overcooking the core.
The flames "lick" the outside of the pan.
Don't know what else to say; I'm not an expert.

Thanks Canishel. I wanted to know if the food got really hot everywhere. I tested a wok with a fried egg at the store for when you make pad thai and fried rice. The egg came out soft but with the brown bits. I think this is the cooktop!!

Homepro01,
Philwojo99 caused me to slap my head. I have the rangetop, not the cooktop. I agree that having knobs on the front face are a good idea, unless you have little ones.

Thanks Philwojo! I do have little ones that spend a lot of time with me. I went to the store today and placed the pans I was most concerned about on the cooktop and range top. The pans overhung about the same amount on both units.

Canishel,
Thanks for the update.

I have the cooktop. The knobs don't bother me. Griddle works fine for pancakes, just have to watch the heat.

I thought I'd resurrect this post and ask for any updates. My biggest concern is the amount of space that the knobs take up. Is there room for a large dutch oven and a few other pans? I don't have room for anything larger than a 30". I'm not certain whether I'm going with a cooktop or a free-standing range yet but am still investigating.

I'm also looking for updates on the Bluestar rangetop and cooktop. I had wanted their 30" range, but it seems as though in the ladt year or so there are more complaints about poor finish work and flimsy sheet metal, so I'm now considering separate ovens. Are there any recent buyers out there who can chime in about quality, etc of the cooktop or rangetop?? Any problems?

I'm also in the process of ordering this now that I squared away my venting. Would love to hear some more feedback!

Be aware that, as of the beginning of this year, Bluestar (Prizer-Painter) has moved to a very large new factory in a nearby town, added new manufacturing equipment and hired a bunch of new employees (including several QA people). In your evaluation be sure to distinguish the new from the older built products.

Aunt Nancy,

When I did the test in a local showroom, I used my 5qt Le Creuset Braiser pan which is 13" round and a 5.5qt Le Creuset Dutch Oven that is 13" round. It was just as roomy as the 30" rangetop for my experience. It was a heavy metal material and was not flimsy at all.

Good luck!
