This is a powerful stove. It heats quickly and performs as expected. I'm enjoying the air fryer. I haven't used all the features like synchronizing burners. The features I have used seem to work well. I do wish the timer alarm was louder. Also the control panel is sensitive to inadvertent touch so I end up locking the control panel when not in use. Overall, I'm happy with the stove so far and it was installed in May 2021. I have not connected to WIFI as I have no reason to at this time. Also, the comments on the app where not that good. I did give it a shot to make the connection but it did not work smoothly and I gave up. Will try again.
