We needed to replace our GE profile oven as it was starting to show some issues (some buttons weren't working, functions, etc but not bad considering it was about 20 years old!) GE has made a quality oven in this model that we purchased. It looks very sleek and modern. It doesn't take very long to heat up (just about 10-12 minutes.) I'll have to test out the convection bake function (probably more for baking cookies), but I did use convection bake to cook a spiral ham for Easter and was slightly disappointed because it didn't seem to have heated it up very much after 1 1/2 hours. I will keep at it. I did roast a chicken and it came out beautifully as did the roast potatoes I've made. I have the app for remote starting the oven which is really cool so when I get home from running my kids places the oven will be preheated ready for dinner to get started. We've only had the oven since March, but am definitely loving it.
