I was eager to purchase this range because of the double oven and was encouraged because , overall, LG does put forth a solid product. Here comes the but....and it's a big one. Others have commented on this as well. The knobs are not the type that you push in to start the flame , therefore , brushing up against it will start the range right up. Scary . I accidentally  did that and thankfully, my arm was not over the range because the flame from  the Ultra Heat started right up. Yes, children could be injured readily.  Don't know why they would not have made this safer just by having the "push in" feature. The other thing is the Ultra heat is installed on both of the front burners, not the back burners  , which would be safer and make more sense. We will be remodeling our kitchen in a couple of years and probably, I will get rid of this range. Just not safe, in my opinion.
