More problems with Bosch spark plugs

[si1491]

has anyone used these https://pulstar.com/pages/how-it-works plugs before? saw them on a Facebook advertisement seem interesting. or are they just another social media gimmick ad?

I have used those. Installed them in my 03 Matrix XR back in maybe 2010 0r 2011? Can't recall exactly when but they are still installed, maybe have put about 50k miles on them since then. No issues at all with them, seem to be good plugs.
