Kenmore Elite digital countertop convection oven is a wonderful addition to our kitchen and home. We bought this about two years ago or so because we wanted something that would heat up quick and we wouldn't have to use our oven for it. This product is just amazing, I have heated up items in there and it takes less than 10 minutes total for it for be cooked and ready to eat. I absolutely love that I do not have to wait 30 minutes to an hour to eat my food. I also love that energy is conserved by using this. I would give it an overall rating of nine because it does very well as a product. The best part is this product is very reasonably priced and heats the food very evenly and quickly. The overall heating I would rate that one a nine. I love that this is also very safe to use and it does not use a lot of energy or power. I would rate the safety and ease of cleaning as a nine. It has been very durable and has not broken down or had any issues the years I have had this. This is a great product overall.
