I am not a light user. Infact, when i built my deck, the number one requirment was easy access to the BBQ 365 days of the year.I live in Airdrie, Alberta where the wind is stong and winters are cold. I BBQ a minimum of twice a week through the coldest months and have never had an issue with temperature. Likewise, in the fall on really windy days, the design of the body keeps all of the drafts out. 

After five years, the starter still lights on the first click. I have even temperatures accross the grills. The outside of the BBQ looks weathered. But like I said, I heat it up twice a week in -10 to -20+ temperatures. 

It was time to replace the castiron grills this fall. I upgraded them to the 9mm gauge statinless steel rod grills. I was really pleased to be able to make the upgrade five years later. so often proudct lines could be discontiued. But because Broil King is not designed as a toss away BBQ they continue to stock parts.
