This oven has been installed about 1 week and we've used both upper and lower ovens for baking bread, lasagna, stuffed peppers and even fries.  So far everything is working great.   We've connected the oven to our home network and google assistant but haven't tried doing anything fancy with those features yet.  For installation, we did have to enlarge the cabinet opening a little, which was quite inconvenient.  Luckily a neighbor recommended someone and he was available to help us.  We have submitted for reimbursement for the cost of modifications from GE based on the fit guarantee.  One week in, we cannot speak to the reliability of the oven but we're hopeful and everything else seems great.
