First issue: the right grate came broken. It was however replaced without any question. It however begs the question of why this broke. 
Customer service was great getting my replacement part. 
2nd issue: I had a professional installer do the install and he complained it was hard to install it with some parts missing that he ended up getting at a local hardware store
Overall: really nice! Looks so slick! Plus having a 5 burner on a 30inch stove is unbeatable
