New to the Blackstone world but I have professionally used flat grills for over 25 years.  My Blackstone performs just like the commercial grills.  Heats quickly, even heat and cleans up even easier than commercial, restaurant grills.  I really like the 2 zone heating ability on my griddle.  Great for cooking breakfast.  Eggs on one side set at lower heat.  Pancakes and breakfast meats on the other side set at a higher temp.
