This range arrived yesterday. I couldn’t wait to try it out. I have used all stove burners, including the warmer burner, and the oven. Everything works great!  The oven is a joy to look at in the gorgeous cobalt blue. Burners heat up so fast, and the oven comes to true temperature in the time specified in the manual ( 10 minutes per 100 degrees). I will be trialing the convection cooking this afternoon.  I am thrilled with this oven!
