Is anybody using e3 spark plugs?

I was just wondering what you think of them.

I've got a set in my 360LA.

They seem to work fine.. dunno if worth the cost over a set of regular plugs.

I think the E3 thing is all marketing. You won't get more spark out of your ignition by adding more ground legs on your plug.

Those plugs make me so much money with small engines!  Customer complaint is engine runs rough, first thing I do is look at the plug if it's one of those E3 plugs , its easy money for me! Customers think "Oh they are 3x the price of a regular Champion , so they must be better ! right? "
Don't waist your time and money!
