I have no issues with how it cooks. 
My issue is the top doors rusted thru in less than four years. Now that I can see inside the door it looks like they have manufactured channels that the water seeps into from the window, and failed to make drain holes for the water to escape. 
If you look at the burner door there are minute holes, but none in the top door or so small the rust particles from inside clog the holes. 
If you own one of these DRILL SOME HOLES!!!

I live in Phoenix metro so it’s not like we get much rain and yet ...
