I've owned this oven for 4 years & love everything about it. It cooks everything but a Thanksgiving turkey, and if I could fit that in there, believe me I would. The oven has never given me any problems. However today I decided to give it a good cleaning, and I ruined the oven with oven cleaner. The interior areas around the door, both on the oven & the door itself are badly damaged from the cleaner I used. I strongly recommend this product, but do not use the overnight-type oven cleaner on the inside of the door, or where the door meets the oven. Or, like me, you'll be purchasing a replacement. I think the oven cleaner inside the oven part did fine - it's just the door frame which is damaged beyond repair. There's a coating inside the door that is eaten away & peeling, so I don't feel it's safe to use now. You will love this oven - just stick to damp cloths or gentle wipe on/wipe off cleaners. I can't wait for my new one to arrive!
