Well, with my move they haven's seen action in almost a year. They do hold up well. Pretty much you just flip them over when they start looking a little cruddy. They create a pretty interesting "infrared" heating pattern and do seem to hold down the flare-ups.

While I DO like how they work, I guess I am enough of a Weber junkie to have never messed with the flavorizer bar design which is the heart of Weber's creation of the Genesis. It would be interesting, though, to try and rig up a lower grate to hold these and try it out!
THIS YEAR MARKS 30 YEARS SINCE WEBER LAUNCHED GENESIS – the gas grill which revolutionized barbecuing like the kettle grill did 33 years earlier.
