Totally insufficient power (BTU) for it's size.  Takes me more than 15 minute to get to a temperature of 450 F.  As soon as you open it, you loose 200 degrees!  Terrible for cooking meat...  The side burner isn't better.  Took me 20 minute to put a gallon of water to boil.  On top of that, I had many problems with this BBQ, they had to send me so repair parts (two times).  Lot of trouble for a very bad BBQ.  Buy an other brand if you don't want trouble.
