No BUT's. Excellent replacement burner for GE model JBP22 0F1AD.  What i received indeed is Genuine GE replacement  part.  The 6" burner I'm replacing has been in use for over 20 years, so I expect long life from this replacement part.  Second, installation went very smoothly.  Installation took longer from removing the old unit ( took longer  (but only because I had to look around for the 1/4-inch hex driver)).  (**Oh, remember ---- turn off the power to the oven before starting work!!!)  .  When installed, the Calrod burner was off-center.  I re-centered without any problem.  I had inspected the mechanism and knew I had secured everything and all movement was of  soft-copper,  not the hard Calrod unit.  Five-stars,  no but's.
