I've had this propane model for 3 yrs. Kept under cover out of weather. Also with BK cover. All stainless steel rusted within 2 months. Replaced grates 3 times with BK grates because of rust. So finally bucked up and bought stainless steel grates. Venturi tubes hole are now bigger in areas so flames are huge in different areas. Cooking is uneven.
I would consider a different brand next time. My neighbor has BBQ thats starts with letter N. 2yrs older than mine and cooks perfect has all original parts.
