Grates are fabulous!  After using my original grates for 10 years these "new and improved" grates are better then I hoped for.  In addition to being completely satisified with the product proformance and price, the best I could find I might add,the speed of Amazon in delivery of the grates was SUPER!!  I have also gotten the replacement burners which were very easy to install thanks to Webers great instructions. Keep up the good work!
