Each person has their specialty. I know next to nothing about medicine, dentistry, accounting etc.
I grew up with a father who spent his life as a professor of mechanical engineering, one of my brothers is a Mech. Eng. too (works in manufacturing) and many of my relatives are electronic engineers etc.
Me, I am a computer geek, and most of my friends work in fields that deal with security, anti-malware etc.
So, to sum up, two main ideas: one, the sensi-temp stuff we've seen prior to 1980's used different technologies (one of them used mercury, I think) and the other one which tried to use a thermocouple did not enjoy the technology we currently have for electronics or microprocessors. If the current sensi-temp this burner uses is a simple thermostat, it should present absolutely *no* problems, it's no different than any thermostats we've been using for decades, temp reaches 450F it switches off, temp falls under 450 it switches on.
The idea I proposed (expanding the sensi-temp to selectable temps) is reliable and being used for at least 2 decades by many high-end stovetops, and it's been inexpensive enough to be used in under $50 portable induction burners.
Second main idea, day in and day out, my friends and I have been observing thousands of *people* who are paid heavily by folks who do not have good intentions to create botnets with hundreds, sometimes thousands of computers infected by malware that spend a lot of time infecting *other* computers to enlarge the botnet, but, mainly, they spend 24x7 trolling and posting disinformation. A lot of them, posting "reviews" on Amazon, Lowe's, HomeDepot etc, extolling some products and excoriating competitors' products.
Unless this new sensi-temp was specifically designed to malfunction to drive folks to smooth tops or gas stovetops, they should work just as well as *any* other thermostats. And until someone I trust comes here on this site and gives a bad review, I will take everything else with a grain of salt.
We do not know the *reason* for those bad reviews. Is it a group of people who hate coil burners and want them banned? Is it some other manufacturer which has not managed to come out with something reliable and time is running out for them to comply with new regulations? Is it people who just love to cause trouble and want to see the whole industry go to shambles so they can buy it for pennies on the dollar?
We do not know.
Just give it a little time, and we will.
I am willing to bet that when regulations forced manufactures to get rid of exposed resistors in favor of either cast-iron burners or Calrod burners, people bitched about it too, and, if we had social networks back then, it would be teeming with folks crying about it too. And, in retrospect, I don't think there is a single thing we miss from those stupid burners which kept failing and putting users in danger.
I don't think we have changed much in just a hundred years. The flies changed, the crap is still the same, if you pardon me my French.
