This replaced a much older double oven (25+ years) and slid into place smoothly; I did the install myself and only had to make one adjustment due to the change in the shape of the rear of the oven.  No problem; was up and running within 2 hours.

The only problem I have with the oven is in the pre-heat time as it takes quite a while to get to the correct temp.  (10 minutes to get to 425!) Otherwise, it works well.  Very easy to use and you can be proficient with the controls in minutes.  This one only has one button for the oven lights, whereas the older unit had one for each oven. The timer alarm is very low and cannot be heard outside of the kitchen; we use Google Home most of the time anyway, so not a problem.
