Overall, this product looks great. I haven't had it long enough to fully test everything, but there are a couple of things I will note from my initial use. 
Even though the burners are bigger than my older stove, I have to turn up the gas higher due to the height of the grates. This makes me think I will use more gas in the long run as they are so far from the bottom of the pans. I could be wrong, but I'm seeing that the burners need to be turned up higher than my old stove to get to the same cooking temps. This will be a learning curve as I could get cooking pretty quickly previously with the burners being closer to the pans. 
Also, the oven light when turned on, has no indication on the LCD screen that it is on. This is a minor issue, and yes I could look into the oven to see if it was on, but it would have been nice to know that when I press it, there was an indication that it actually went on.
