Our Master Chef G45311 BBQ burners and covers were rusted out when we uncovered it after a very snowy winter. They were very expense at other stores and from the manufacturer so I tried these instead in the hope I could get them to work. The slit at the top of the burners was 2mm too short to slide the burner on, so I used my Dremmel tool to make the slit a bit longer but I may have been able to use small metal file instead. We didn't use the pins as our bbq is stationary. Burner covers and cross pieces worked well. I could not fit the automatic starter- had to wire it to a burner with stainless steel wire, but it works fine anyways. I would get this again. Felt good being able to reuse our bbq rather than having to get a new one and was much cheaper than a replacement.
