Product review (5 stars): very impressed
I bought this product so I could move all my cooking outside to my porch.  I live in central Texas, and it's been really hot this year.  I already have a countertop convection oven, an electric frypan, a rice cooker and deep fryer, so this is the last piece I need.  I found the cooktop to be intuitive and easy to use and it looks great.  I was especially impressed with the one piece stainless steel frame, as well as the black glass top and control panel.  The covered non-stick frypan they include is nice too.
So I first used it to make Thai basil soup.  It did this well, although it's not especially challenging.  After that I picked almost 6 gallons of wild grapes which I cooked down in 2 batches to make juice.  I was impressed with how quickly it brought the grapes up to a boil.  I then made jelly with the juice.  I brought 5 cups of juice with pectin up to a rolling boil, added the 7 cups of sugar, back up to a rolling boil for a few minutes, and was done in 15 minutes.  That's better than my stovetop.  This thing is a workhorse.  I have made breakfast with it, but still seem to char the bacon a bit.  I have also used it to cook 12 quarts of salsa and then boil-process the jars (the timed cook feature is really nice for that).  Also made stir-fry with my carbon steel wok at highest setting and got really good results.  So far I'm totally impressed, I just hope it doesn't break.  I've put it to some pretty serious use for a week, with a lot more to come, as I still have lots of tomato vines coming into production.
Just to update, over the last two years I used this cooker to can everything.  I have used it to can 10 quarts and 18 pints of green beans, 20 pints of tomato sauce. 18 pints of pear sauce, 18 pints of squash relish, 20 pints of homemade sauerkraut, some prickly pear jam, I don't know what else.  This is my go-to appliance for serious work.  I still love it.
