Just got a response from Steve with regards to this thread:
you have installed 4-5 you bought 2, if you are making your own
and selling, you are infringing the patent, just want to let you know, and
these are not automotive parts!
The parts are made by a company under my account with them, Patent is in
place for a purpose!
Hey Steve, you sent me two for free to try out remember?
Second email...
Thanks for the bashing
! and,all the patent BS talk on here, let me tell
all your readers it is patented and most of these guys bad talking the
product have left their customers stove not fully cleaned as they have told
me, it works well in places they usually cant get to and just leave those
areas dirty! alot of BS talk on this site!
oh and by the way make your own and sell it, I can make money selling mine
or suing for infringment no big deal!................
