When I first received my flavorizer bars, there was entirely too much snow surrounding the grill to consider firing it up for a trial.  Then the snow and ice melted, and my flank steak was first on the grill, to be followed by burgers.  Back to grilling in winter!  Thank you so much for quick delivery and ease in installation, I am looking forward to many more evenings of grilling with my Weber Spirit Grill fully operational once more!
