I bought this a month ago after researching a lot of electric ranges . As of now I am super happy with it . Very even baking and convection is great !! I love the instant view . The reviews are true that the knobs go on if bumped into but I just lock them (so easy to do ) and problem solved . I have not as of yet used the airfryer . This replaced an lg range that was 9 years old and still working well . The blue interior is beautiful . It looks very high end in my kitchen . Hoping to have it for years to come and as of now am very happy with my purchase !!
