Did the research and decided this was the one that fit, as mine is a build in, and met my wants. But it had to be ordered. No problem. My oven still kinda worked. I ordered at the end of October and took delivery in April. I’m pleased with everything about this oven. It’s quite. Thank you. It cooks evenly. Best cookies ever. That’s per my grandson. The broiler is a beast beware. When using the broiler try the low setting or be vigilant. I’ve tried all of the features and every one has performed beautifully. There is an app that come with this this. I haven’t used it. I see it could be used for preheating if you’re coming in hot from work. But other than that I’m not sure it’s overly necessary. Lastly I’d say it heats up to temp within minutes. There is no long delay to wait for it to heat. This was great buy.
