This is my second GE Profile double range ( thus one purchased for my mom) there are a few upgrades since my new one purchased almost 2yrs ago. thus one has the air fryer & the cooktop has the RIM around the perimeter— which surprisingly I love! Books great, warms fast! Love the knobs! Now the only disappointment s this one, mind came a Two rollout racks! This one has none! that’s a HUGE disappointment b/c I LOVE those rollout features to get food more easily without burning your arms! Otherwise love this oven & what we lovingly refer to as the “ pizza oven” b/c great gif warning foods snd cooking when not necess to warm the entire house!  Great! Just LOVE GE Profile products!!!
